Abstract: A hydrophilic material comprising a copolymer composed of a monomer (A) having a polyalkylene oxide unit and a polymerizable carbon-carbon double bond in its molecule, a methacrylate or acrylate monomer (B) and another monomer (C) having a polymerizable carbon-carbon double bond in its molecule, which material is characterized by containing the monomer (C) in the proportion of 10 to 90 % by weight. The invention provides a hydrophilic material which is soluble, readily moldable, and excellent in antithrombotic and antifouling properties, and further provides an antithrombotic material and a semipermeable membrane. These materials can be appropriately used in the medical field and as water-absorbent and antifouling materials.

Abstract: An antithrombotic blood treating system comprising a combination of a permselective hollow fiber membrane containing a copolymer having a polyethylene oxide unit; a header having a blood-contacting surface coated with either a heparinized hydrophilic copolymer containing vinyl chloride as the constituent or a hydrophilic copolymer having a polyethylene oxide unit; a catheter; and a circuit. It becomes possible for the first time to conduct extracorporeal circulation for a long period of time without the necessity for internally administering heparin by imparting an antithrombotic property to the entire blood-contacting surface.

Abstract: Disclosed is a hydrophilic material characterized in that the material comprises a copolymer composed of a monomer (A) having a polyalkylene oxide unit and a polymerizable carboncarbon double bond in its molecule, a methacrylic ester monomer or an acrylic ester monomer (B) and a monomer (C) having a polymerizable carbon-carbon double bond other than the monomers (A) and (B), and the content of the monomer (C) is not less than 5% by weight and not more than 90% by weight, and a semipermeable membrane made therefrom. The present invention provides a hydrophilic material which can be dissolved in a solvent, can be easily formed and is excellent in antithrombotic and antifouling properties, and further provides an antithrombotic material and a semipermeable membrane. These materials can be appropriately used in the medical field and as water-absorbent and antifouling materials. - 4 6
