Process for the preparation of ethylenic silicon compounds containing functional groups

Organosilicon compounds containing a silicon atom to which are connected two methyl groups, one vinyl or allyl group and a p-(nitro or methoxycarbonyl)phenoxymethyl group are prepared by an etherification reaction between vinyl(or allyl)dimethylsilylmethyl chloride and sodium p-nitro(or methoxycarbonyl)phenoxide. The nitro group can then be reduced to the amino group and the methoxycarbonyl group can then be hydrolysed to the carboxyl group. The organosilicon compounds thus obtained, which contain an ethylene group and another reactive group, are useful for the preparation of unsaturated disilanes which are intermediates in the manufacture of silicone elastomers.

Process for the preparation of new thermoplastic elastomers

An alpha , omega -dihydropolydimethylsiloxane of molecular mass of approximately 1000-2000 is polymerised with a compound containing a polyaromatic linear chain terminated by a vinyldimethylsilylmethoxy group at each end. The thermoplastic elastomers thus obtained are usable for the manufacture of articles formed by extrusion or injection in the molten state, and of films by evaporation of their toluene solutions.

Process for the preparation of polyethylenic silicon compounds

Organosilicon compounds are prepared, the molecule of which contains two Si atoms each carrying a vinyl or allyl group and connected to each other via a hydrocarbon chain interrupted by O, S or N atoms and via at least one amide, imide or urea group. The process consists in condensing, with itself, a monosilicon compound carrying, at the chain end, radicals which form amide, imide or urea groups. For example, 1-amino-4-(vinyldimethylsilylmethoxy)benzene is reacted with terephthaloyl chloride to produce the product of the formula below. By adding these organosilicon products containing two olefinic double bonds to alpha , omega -dihydrogenpolydimethylsiloxanes, block copolymers are obtained which are thermoplastic and meltable silicone elastomers. ...

Thermoplastic elastomers containing an oligopeptide hard component

The present invention is generally directed to a new class of TPEs made from peptide terminated low T g polymers and methods for making them. The middle block of these TPE is a telechelic polymer with a T g that is below the intended service temperature of the TPE. The terminal peptide segments of these TPEs are short (from about 1 to about 10 amino acids long) and tend to from sheet type secondary structures through intermolecular hydrogen bonds, creating physical crosslinks between polymer chains. The dissimilarity of the peptide hard component and the elastomeric soft component results in very strong segregation between the microphase domains and a low plastic deformation for the resulting TPE. And since the T m of the crystalline peptide phase can be adjusted, these new TPEs may be tailored to fit the intended service temperature and are melt-processable.
