Patent ID: 7129321

Claim:
A polymerizable composition comprising: a) at least one first polymerizable component further defined as a monomer having at least two functional groups, the functional groups further defined as cyanato, isocyanato, thiocyanato, isothiocyanato, (meth)acryloyl, thio(meth)acryloyl, and/or episulfide radicals, and b) at least one second polymerizable component further defined as: i) thiophosphine monomers of formula: wherein X represents —SH or with R 1 being H or —CH 3 , R and R′ represent, independently from each other, an alkyl radical, an alkoxy radical or a phenyl radical which may be substituted with one or more alkyl and/or alkoxy groups, n is an integer from 0 to 4, n′ is an integer from 0 to 5, x is an integer from 0 to 2; and y is an integer from 1 to 5 with the proviso that y+n is an integer from 1 to 5; or ii) prepolymers resulting from the polymerization of at least one of said thiophosphine monomers of formula (I) and at least one of said first polymerizable component.
