PHASE SEPARATED, BRANCHED, COPOLYMER HYDROGEL

摘要

The present invention provides a hydrogel composition comprising a mixture of a hydrophilic polymer and a polymer chain modifying agent, wherein the polymer chain modifying agent is selected from the group consisting of an aromatic tetracarboxylic dianhydride, a titanate, and a polyetherimide. The present invention also provides a method for producing a phase separated, branched, copolymer hydrogel comprising a mixture of a hydrophilic polymer and a polymer chain modifying agent. The present invention also provides an implantable medical device comprising a phase separated, branched, copolymer hydrogel wherein the phase separated, branched, copolymer hydrogel is formed of a hydrophilic polymer and a polymer chain modifying agent.
