Abstract
Materials for forming a hydrogel when contacted with water having improved anti-thrombogenic properties and a highly improved mechanical strength are obtained by the copolymerization of a free radical-polymerizable vinyl monomer capable of forming a hydrophilic polymer and a hydrophobic macromolecular compound having a chain-terminated polymerizable double bond and a molecular weight of 1,000 to 100,000.
