The invention concerns a procedure for the production of gesehäumter zellularer polymer materials, in which Canadian patent writing NR, 873718 becomes new sehäumbare compositions descriptive, which at least a polymerizable Vinyl more ther, which contains at least two Vinylgmppen per molecule, a sudsy means, acids a catalyst and if necessary at least a connection, like e.g. a mehzweräges phenol and an aliphatic multi-valued alcohol, reactive with the Vinyläther, contains a epoxydiertes material, a Polycarbonsäure, a PP or a Polyearbamat. The composition supplies ge.schäumte zellulare polymer materials, which are superior to the well-known PU regarding the toxicity of the components and the well-known polystyrene foams regarding their suitability for sudsy at place and SteUe. Despite more ibxer numerous useful characteristics to stretch the new foams look rapid and härret rapidly, so that it is difficult, large areas with a gleichrnäßig trained tear-free foam to auszumüllen, to many of the new foams mentioned are missing the resilience, them have brilehige surfaces and are dimension unstable, if they are present in a form with low density. It was determined now the following.: If with the above types of foamable compositions of the Vinyläther first with the component under formation of a Vorpolymeren, reaküven with Vinyläther, one converts, the foams, which are made of this Vorpolymer component under mixture with a sudsy means and satires a catalyst with or without zustauchen Vinylälher and more bzw.oder with Vinyläther reactive connections, possess an längex e Reaktlonszelt forwards to that-to-harden, better resilience, good surface finish, better Hafffestlgkeit and are stable dlmensions=, even if they are present in a form with small density. A goal of the invention is therefore the creation of foamable compositions and foamed zellularer polymer materials, which are also based on polynlerisierburem Vinyläther, which mindestem two Vinylgruppen per molecule contain, in mixture with Vinyläther reactive connections. A further goal of the invention is the production of such foamed zeUutarer polymer materials, which exhibit the favorable characteristics longer reaction tent, good surface finish, good adhesive strength, increased resilience and dimensional stability with forms with low density. The invention concerns from there a procedure for the production of foamed zellularer polymer materials, which is characterized by it, at least dal one 1. a Vorpolymer, which became by conversion by mindestem more polymerisierbarenVinyläther, which at least two Vinylgmppen per molecule contain, with a connection, selected to the group of alcohols, reactive with Vinyläther, mehnqertige phenol, carbonic acids, Polyearbamate and Polyamid%hergestellt, 9 a flüehüges Sehäumungsmittel and 3. one rushes catalyst zusammenmiseht and the mixture lets foam. Vorzugsweisewiß of the Misehung at least one connection from the group, which from a polymerizable Vinylätber, which epoxydierten contains at least two Vinylgmppen per molecule, phenol being DNN gene, aliphatic alcohols, materials, which contain at least a Epoxygmppe per molecule, Polyearbonsänsen, PP, Polycarbamaten and polymerizable B-äthylenisch unge ttigten connections exists, incorporates. It was found that it is favorable to use the components for the production of Vorpelymeren in accordance with the invention in such Verhälmissen that for each molecule of the Vinyläthers at least a reactive group of the connection reactive with Vinyläther is available. The characteristics of the foamed product depended on the equivalent weight of the Vorpelymeren. For example on use of a meb.rwertigen alcohol as connection rigid foam reactive with Vinyläther are received, if the equivalent weight of the Vorpolymeren amounts to less than 270 per Vinyläthergruppe| halbstarm foams, which require a Ofenheizung, are received, if the equivalent weight of the Vorpolymeren 2q0 - 3fi0 proVinyläthergmppe is; one receives flexible foams, which are foamable only in a furnace with 60 to 80°C, if the Äquivalentgewfeht of the Vorpolymeren over aB0 per Vinyläthe.rgmppe besägt. In case of these flexible foams the viscosity of the Vorpolymeren is critical: 18 if the viscosity is too low, escapes the sudsy means, if the viscosity is too high, inferior foams are kept premature. For flexible foams a suitable Viskosi is appropriate for this kind uberetch for the Vo more olymer between 30 and 60 Poises at room temperature the Vorpolymer can 35 - Gew, - % of the foamable compositions in accordance with the invention constitute. The foamable compositions gemäht the invention can also flaming timer, oberfläehenakrlve materials, coloring materials, fillers. Stabilizers, Antioxydantien, Weiehmaeher and Viskositätsregler contain. Polymerize-cash Vinyläther, which is suitable in accordance with the invention for the use in the foamable compositions, is such, in which two or more Vinylgruppen are bound at one Äther-Sauer28 each material atom.

It was found that the geradkettigen Vlnyl is more ther more reaküonsfäMger than dte verzweigtksttigen or cyelischen Vinyläther. The Vinyl thergruppen in the molecule can directly or different be. It is desirable that the Vinyläther does not simmer during the foaming power reaction. The allphaüschen univalent or multi-valued alcohol components of the Vorpolymeren of the sehäumbasen compositions gemäl3 of the invention cover amyl alcohol, 2-Äthylhexylalkohol, Nonylalkohol, n-Decylalkohol, ethylen glycol, propylene glycol, 1, B-Butylenglykol, Diäthylenglykol, 1,4-Butandiol 1, 5-Pentandtol Neopentylglykol, Glyeerin, 1, 2, 6-Hexantriol, Trimethyloläthan, Trimethylolpropan, castor-oil, Pentaerythrit, sugar alcohols, Znckeralkohol Alkylenoxyd Kondensatiousprodukte and hydroxylhaltige esters and polyester, which will receive acids by condensation from multi-valued alcohols and color mixing. The multi-valued phenol components of the Vorpolymeren cover Resomin, Brenzcatechin, Hydrochinon, 2: 2-Dl-pi-hydroxyphenylpropaß Phloroglncin, polycarbonates with low Moleknlargewieht, which contain phenolic hydroxyl final's groups, Kondensationspmdukte of Phenolen with aldehydes and Ketonen etc. Suitable Polycarbonsäure components of the Vo olymere cover Bernsteinsänre, Glutarsäure, Adipinsäare, Azelains ure, mark in the ure, fumaric acid, Itacousäure, Phthalsäur% Isophthalsäure, Terephthalsäure, Trimellitsäure, Trimesinsäum and Ghlorendsänre (1, 4, 5, 6, 7, 7-Hexach! orobicy 1o [2, 2, 1] -5-heuten-2, 3-dicarbonsäure) and polymerized insatiated fatty acids such as Dimerund rubble-pure and carboxylgmppenhaltige esters and polyesters. For the Vorpolymere suitable Polycarbamat components e.g. cover themselves connections, from organic Polyisocyanaten and Polyolen ableiten° like the Kondeusationsprodukt of Tolylendiisocyanat and 1, 5-Pentandiol of the formula: HO - (C) s. _ _ - 0 - C - l II o H 2 \ NH-C-O (CH2) s-O-C-NH tl IL o o CHs I --NH - C - O - (CH2) 5OH --/flat steel bar o in which n a whole number of at the most 3 is, and the condensation product of diphenylmethan -4,4-diisecyanat with low Molekulaxgewieht and polypropylene glycol with a Molekulargewlcht of 425. As PP the Diarnide, of dimeäsierten linseed oil acids is derived and the formula the H2N is -- - (CH2) 34 II o o exhibit and the PP, which is derived from Isophthalsäure and Pentamethylendiamin, suitably. The Vorpolymer can be manufactured by simple mixture of the components. Accelerate the reaction by warming up in certain FäUen kaunman. It is favorable mostly, one drinks Kakatalysator such as p-Toluolsulfosäum to use hydrochloric acid or sulfuric acid. When flüehüge Schäumungsmlttel is for use with the sehäumbaren compositions in accordance with those identification such means suitably, which are in the other components of the sehäumbaren Zusammensetzuagen solubly or disperglerbar and sufficient volatile, so that they evaporate during the education of the foamed Polymermateäalien. The warmth of the katalyäerten polymerization reaction causes that the Schänmungsrnittel begins to simmer, and the developing steam forms gas bubbles, which see during the Polymefisaüonsreaktion under education of a gesehäumten polyrnerlsierten mass with low density to expand. As Sehäumungsmittel halogenierte hydrocarbons are preferred such as Trlehlormonofluormethan, Diehlortetrafluoiäthan, tri chlorine tri fluorine ethane, Dibromdifluormethan, Diehlorhexafluomyelobutan, Methylenehlortd, Cb.loroform, trichlorethylene, Tetraehlorkohlenstoff and tetrachlorethylene. Those rush catalysts, which are suitable for the activation of the foaming power reaction, cover the strong proton donor acids such as p-Toluolsulfonsäuse and the Lewissäusen such as Bortriftuortd, which be suitable-proves as Ätherate is used. Compositions, which very reaküve Vinyläther to contain, how Butandiot Divinyläther can by p-Toluolsulfosäuse are e.g. catalyzed, but ate catalyst for that Zusammemetzungen, which include-borrowed 3, 4-Dihydro-2H-pyranylverbindungen the 3,4-Dihydro-2H-pyran-2-methyl (3,4-dihydro-2H-pyran-2-eaxboxylat) contains, a Lewissäure preferred. One can adjust the Schaumbildungsreakläon by use of catalyst combinations, e.g. p-Toluolsulfosäure and boron tri fluoride or Bortrifluorld and Trimethoxyboroxin.

It is günstib the catalyst in quantities of 0, 005 to 2, 0 thread - % of the compositions to use, however these quantity specifications are not restrictivy, there the catalyst quantity depending upon the reaction temperature and the necessary Selääumtmgs Induktionszeit to be adjusted o11. The catalysts used with proceeding in accordance with the invention become as 5 - 50%ige solutions inLösungsmitteln uses, e.g. as solutions in mono ethyl ethers of ethylen glycol, the mono ethyl ether of Diäthylenglykol, Nitromethart, Nitmbenzol, Butyrolaeton, Aeeton, n-butanol more oderDiäthyläther. As flame-retarding means for training into the sehäumbaren Zusammemetzungen tri chlorine ethyl phosphate, 2:2 - ice (3 ', 5 ' - is dibrom-4' hydroxyphenyl) prop.-ate trichloroethylene (dibrompropyl) phosphane chlorine final acid and Polyvlnylchlorid with or without antimony oxide been suitable. The Phenolverblndung nnd the ¢hlorendsäure serves both and F1ammverzögerungsrnittel and with Vinyläther reactive Materlalien. Before-pulled as surface-active materials such connections, which belong to the type of silicone, Belsptele are indicated in the Belgian Patentsehriften Nt.582362 and No. 584029, i.e. that they belong to the Siloxun Oxyalkylen Copolymertyp. Into the sehäumbaren compositions in accordance with the invention also or several know niehtzea a erte polymerizable Vinyläther, which contain at least two Vinylgruppen per molecule, or one or more connections, which are trained with the Vinyläthern reactively or eopolymeriäerbar SI, ld. As polymerizable Vinyläther for training into the compositions in accordance with the invention for example the polymerizable Vinyläther specified above is suitable. Connections, which are with the polymerizable Vinyläthern mentioned reactive or copolymerisierbar and were found for training into the compositions in accordance with the invention as particularly suitably, cover phenol connections, aliphatisohe univalent and multi-valued alcohols, epoxydierte materials with at least a Epoxygruppe per molecule, sour connections with at least two groups of carbon acids per molecule, Amidoverbindnngen with at least two Amidogmppen per molecule, Carbamate with mindestem two Carbamatgmppen per molecule and polyme” Islerbare, o - monoäthylenlseh insatiated connections. Belsplele for phenol connections, aliphatic univalent and multi-valued alcohols, Polycarbensäure.n, Amidogruppen with at least two Amidogruppen per molecule and C arbamate with at least two Catbamatgruppen per molecule, which can be trained, are indicated above. Under “epoxydierte materials with mindestem of a Epoxygruppe per molecule” to be trained, are connections know to be understood, at least one group of the formula I I - C - C - o per molecule contain. Examples of such connections are Epiehlo” hyddn, styrene oxide, Diallyläthermonoxyd, Cyelohexenoxyd, Glycidylphenyläther, Glyeidylstearat, Dnpentendioxyd, Vinyleyelohexendioxyd, Polyallylglyeidyläther, Diphenylolpropandiglyeidyläther, epoxydiertes polybutadiene, epoxydiertes styrene Bntadieneopolymere, the resin-like Kondensationslxodukte of Epiehlorohydrin and aliphatisehen or aromatic Polyolen such as Glyeerin or 2, 2-IX-p-hydroxyphenylp” opun etc. Examples of polymeriäerbare A, 13-monoäthylenisch insatiated connections are 3, 4-Dihydro -2H-pyran, 2-Äthoxy-3, 4-dihydro-2H-pyrun, 2-Alkyl-3, 4-dihydro-2H-pyran, 2 - Phenyl3, 4-dihydro-2H-pyrun, 1-Deeen, Vinylstearat, Laurylvinyläther, Dibutylmaleat, Maleinsäureanhydzid, Vinylcyelohexen, Alkylaerylate, Alkylmethacrylate, styrene, etc., then in accordance with the foamable compositions can contain catalyst and Sehänmungsmittel a portion on of the Erirmdung in addition vorgebildetenReaktiomprodukt, urtreagiertexn IXvinyläther and one with this reaktlvenVerblndung. The use of different portions of such materials supply compositions, which lead to the education of gesehäurmer materials with very different self-scolded. In order to receive foamed materials with favourable characteristics, which are suitable fär certain purposes. it is necessary to vary the portions of trained reaction product and of the other active component in accordance with the kind of the trained reaction product and the other active components. The production of the Sohaumstoffe in accordance with the invention with the help of a preceding formation of a Vorpolymers supplies foam materials, which are superior to those, which are won directly from the foaming components without the Zwisohenstufe of the polymer formation. The improved SchaumS0 of materials in accordance with the invention has larger resilience, better Oberfläehenbesohaffenheit, and a longer sound duration with the sudsy. In addition one can use the procedure in accordance with the invention for the production of Sehaumstoffen, which are dimension stable with decreased density. It is to be accepted that the use of Vorpolymeren causes a change of the Reaktiomprozesses with the Sch umungsvorgang. The components of the sehäumbaren compositions can be poured by agitating in a container gerräsehr and afterwards rapidly into a form. Sometimes it is favorable to warm up the composition in the form in order to support the formation of the foam. The scb31umenden Bestandteiie can be mixed also in the container, which is to be filled with the foam, if it permits its form. If mixing the components takes place under agitating, then an additive one is surface-actively “n of material favorable for composition very, in order to receive foam materials with small lines. However an surface-active material is not always substantial. For example the components are mixed with certain sehaumentblndenden machines under pressure and using a Sehäumungsmittels, which is gaseous with the Misehtemperatur, whereby the adjustable pressure is waived, and the “frozen” mixture is then distributed at the time of the use. In such “Einfrier' device is a oberfläehenaktives means avenges substantially. However it is with the usual machines in which the foamable compositions relieved become, before the sudsy begins, which became use of a oberflächenakttven material often desirably, with the Nachaxbeitung of many prescriptions found that the reduction of the quantity supplies material at the time, at soft the blisters straight to burst surface-actively on, if the Polymeflsation is terminated Sohäume, which exhibit the well-known “open” cell structure. The foam materials in accordance with the invention in flexible form can the padding, mattresses etc. are used.
