Patent ID: 8043369

Claim:
A biomedical device comprising a polymerization product of a mixture comprising (a) a siloxane-containing homopolymer comprising a thio carbonyl thio fragments of a reversible addition fragmentation chain transfer (RAFT) agent; and (b) one or more biomedical device-forming comonomers, wherein the siloxane-containing homopolymer is of the general formula: wherein L is a linking group, R 10 and R 11 are independently hydrogen, a straight or branched C 1 -C 30 alkyl group, a C 1 -C 30 fluoroalkyl group, a C 1 -C 20 ester-containing group, an alkyl ether group, cycloalkyl ether group, cycloalkenyl ether group, aryl ether group, arylalkyl ether group, a substituted or unsubstituted C 1 -C 30 alkoxy group, a substituted or unsubstituted C 3 -C 30 cycloalkyl group, a substituted or unsubstituted C 3 -C 30 cycloalkylalkyl group, a substituted or unsubstituted C 3 -C 30 cycloalkenyl group, a substituted or unsubstituted C 5 -C 30 aryl group, a substituted or unsubstituted C 5 -C 30 arylalkyl group, a substituted or unsubstituted C 5 -C 30 heteroaryl group, a substituted or unsubstituted C 3 -C 30 heterocyclic ring, a substituted or unsubstituted C 4 -C 30 heterocyclolalkyl group, a substituted or unsubstituted C 6 -C 30 heteroarylalkyl group, fluorine, a C 5 -C 30 fluoroaryl group, a siloxy group, or a hydroxyl group; n is from 2 to 100, and A is a thio carbonyl thio fragment of the RAFT agent.
