Abstract
Copolymers are manufactured to include a zwitterionic monomer (e.g., methacryloyloxyethyl phosphorylcholine monomer), a dihydroxyphenyl derivatized monomer, and optionally one or more additional monomers. The dihydroxyphenyl derivatized monomer gives the copolymers excellent adhesion properties. Optional monomers include a cationic amino monomer, a hydrocarbon monomer, and/or a hydrophilic monomer. The copolymers are biocompatible and can be used with medical devices.
