title: Polymer structure and blood compatibility evaluation - application of an acrylonitrile copolymer.
abstract: An acrylonitrile-dimethylaminoethyl methacrylate copolymer has been synthesised by a straightforward procedure. The cationic nature of the copolymer permits ready attachement of heparin and reaction of the copolymer with ethylene oxide gas allows a controlled alteration in chemical structure. These featues of the copolymer are discussed with respect to the influence of polymer properties on blood compatibility as exemplified by blood platelet retention.
