Patent ID: 7884171

Claim:
A polymeric composition of matter having the formula A[BC] n Z wherein B is at least one polymeric block selected from the group consisting of polyurethanes, polyureas, polyamides, aromatic polyesters, aromatic polycarbonates, polystyrenes, and polyacrylates, C is at least one polymeric block selected from the group consisting of polyethers, silicones, aliphatic polyesters, polyisoprenes, optionally-hydrogenated polyisoprenes, polyisobutylenes, optionally-hydrogenated polybutadienes, polyethylenebutylenes, and aliphatic polycarbonates, A is a surface active endgroup selected from the group consisting of polydimethylsiloxane chains and poly(ethylene oxide) chains having one or more amino-, hydroxyl-, carboxyl-, phosphoryl choline-, acryloxy-, or methacryloxy-containing moieties along the chain or at the terminal position thereof, and Z is a surface active endgroup that may be the same as or different from A, or mixtures of said A, B, C and Z, wherein n is a number from 5 through 10 5 , and wherein said polymeric composition of matter has a weight average molecular weight in the range 5000-5,000,000 daltons.
