Abstract
Provided is an antithrombogenic biomedical material comprising a copolymer of (A) not less than 5% by weight of one or more polymerizable monomers having a polyethylene oxide unit with a degree of polymerization not less than 5 and a polymerizable carbon-carbon double bond and (B) not more than 95% by weight of one or more monomers copolymerizable with said monomer (A).
Claims9
An antithrombogenic biomedical material comprising a graft copolymer obtained by graft copolymerization not less than 5% by weight, based on total weight of the monomers constituting the graft copolymer, of one or more polymerizable monomers (A) having a polyethylene oxide unit with a degree of polymerization not less than 5 and a polymerizable carbon-carbon double bond onto a polymer (B) obtained by polymerization of one or more monomers copolymerizable with the monomer or monomers A, wherein said polymer (B) is a polymer or copolymer containing not less than 10% by weight, in terms of monomer, of vinyl chloride units.
