Reaction between isocyanate groups and active hydrogens is induced preferentially to reaction with a small amount of water in the mixture by means of a catalyst, for example a mono-organic-mercuric compound. When the mixture attains a viscosity of at least 50,000 centipoises, its composition is so chosen that reaction between the water and the isocyanate groups now takes place aided by a further catalyst, producing carbon dioxide sufficient to expand the mixture to 105-125% of its original size, so that the cable is firmly blocked. Materials used to form the block are disclosed.

A process for preparing a polyurethane polymer comprises the step of: 115.-. (canceled)16. A process for preparing a polyurethane polymer , comprising the step of:I) mixing a first reactant component comprising a polyisocyanate with a second reactant component comprising a compound having Zerewitinoff-active hydrogen atoms in a mixing vessel to obtain a reaction mixture,whereinthe first reactant component and/or the second reactant component are contacted with a catalyst bed before they are mixed in the mixing vesseland/orthe reaction mixture is contacted with a catalyst bed,wherein the catalyst bed contains a catalyst reversibly sorbed on a substrate,the catalyst catalyses the reaction of isocyanate groups with themselves or with Zerewitinoff-active compounds,and the catalyst is released into the first component, second component or reaction mixture that is in contact with the catalyst bed,such that a reaction mixture containing the catalyst is obtained.17. The process according to claim 16 , wherein:a stream of the first reactant component is combined with a stream of the second reaction component in a mixer to obtain a stream of the reaction mixtureandat least one stream selected from the stream of the first reactant component, the stream of the second reactant component and the stream of the reaction mixture flows through the catalyst bed,such that the catalyst is released into the stream that flows through the catalyst bed.18. The process according to claim 16 , wherein the catalyst is released in such a way that the reaction mixture containing the catalyst contains the catalyst in a proportion of ≥1 ppm to ≤5000 ppm claim 16 , based on the weight of the reaction mixture.19. The process according to claim 16 , wherein the reaction mixture comes into contact with the catalyst bed claim 16 , and the first and second reactant components do not come into contact with the catalyst bed.20. The process according to claim 16 , wherein the first and second reactant ...

(Cyclo)aliphatic di-isocyanate-based polyisocyanate mixtures with alkoxy groups, in which the alkoxy groups are a component of an allophanate group and possibly a urethane group, with more than 50 mol% of the alkoxy groups in allophanate groups and linked via the allophanate group with at least 2 polyisocyanate molecules made up of at least 2 di-isocyanates. Polyisocyanate mixtures based on aliphatic and/or cycloaliphatic di-isocyanates, with an average isocyanate functionality (AIF) of at least 2, an NCO group content of 4.0-28.0 wt% and a 1-36C alkoxy group content of 2.0-37.5 wt%, in which the alkoxy groups are components of an allophanate group and possibly a urethane group, with more than 50 mol% of the alkoxy groups forming components of allophanate groups and linked via the allophanate group with at least two polyisocyanate molecules, each of which is made up of at least two di-isocyanates. Independent claims are also included for: (1) similar polyisocyanate mixtures with an AIF of 2.3-9.9, an NCO group content of 5.0-24.0 wt% and a 1-36C alkoxy group content of 3.0-29.0 wt%; and (2) a process for the production of these mixtures by reacting (A) a polyisocyanate component with an AIF of 2.0-5.0, a (cyclo)aliphatic NCO group content of 8.0-27.0 wt% and a monomeric di-isocyanate content of less than 1 wt% with (B) 1-36C alcohols at an NCO/OH equivalent ratio of (1.9:1)-(80:1) so that more than 50% of the initially-formed urethane groups undergo further reaction to allophanate groups.

Catalyst and method of making polyurethane materials

Номер: WO2005058996A1
Принадлежит: JOHNSON MATTHEY PLC

The invention is a catalyst composition which is suitable for use in catalysing the reaction between a polyol and an isocyanate composition comprising a mixture of a) an organotitanium or organozirconium compound and b) a bismuth compound, optionally in the presence of an amine. The catalyst composition is especially useful for curing polyurethane-forming mixtures in which the polyol component contains secondary hydroxyl groups.
