Patent ID: 7494665

Claim:
A biocompatible polymer comprising siloxane monomers that impart flexibility to the polymer and monomers that impart mechanical strength to the polymer wherein the polymer has the structure of formula I: wherein m and n are independently positive integers, wherein X is an absence, a linking group, a biobeneficial moiety or optionally a bioactive agent, and wherein A is an absence, a biobeneficial moiety or optionally a bioactive agent, wherein the siloxane monomer is derived from a compound having the formula of where R 1 and R 2 are independently H, F, Cl, Br, I, C1-C10 alkyl, C3-C10 cycloalkyl, substituted C1-C10 alkyl, haloalkyl, fluoroalkyl, chloroalkyl, bromoalkyl, iodoalkyl, phenyl, substituted phenyl, alkoxyphenyl, halophenyl and alkylphenyl, aryl, or substituted aryl, alkoxyaryl, haloaryl and alkylaryl, and Z 1 and Z 2 are independently absence or oxygen (O).
