title: Antithrombogenic heparinized polyacrylonitrile copolymer.
abstract: A new antithrombogenic polymer was synthesized by the photograft-copolymerization of methoxypolyethyleneglycol methacrylate and dimethylaminoethyl methacrylate to polyacrylonitrile containing bromine atoms, and by quaternizing and heparinizing the graft-copolymer. Hydrophilicity and heparin content of the polymer could be controlled by changing the feed ratio of the acrylates to be grafted. The heparinized polymer showed excellent mechanical and antithrombogenic properties.
