    Abstract: A hollow polysulfonic fiber intended for a selectively transmissive membrane contains a hydrophilic polymer which is cross-linked into a water-insoluble form (for example polyvinylpyrrolidone) and is used in the form of a hydrogel containing water. A method for the production of a membrane module consists in spinning a hollow fiber by the use of a spinning solution containing a polysulfonic resin and a hydrophilic polymer, wetting the fiber above the saturated moisture content, and then, with the wet condition maintained, subjecting the fiber to the processes of module molding and radiation induced cross-linking, these processes being performed in either order.

    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: PCT No. PCT/JP82/00422 Sec. 371 Date Jun. 30, 1983 Sec. 102(e) Date Jun. 30, 1983 PCT Filed Oct. 28, 1982 PCT Pub. No. WO83/01632 PCT Pub. Date May 11, 1983.The present invention relates to a hollow fiber type ultrafiltration membrane comprising a material of polymethyl methacrylate series in which no crosslinking is formed substantially and a process for its preparation. By employing adequate conditions, this material which is easy to handle makes it possible to achieve a steady manufacturing process and a constant quality of product. The obtained membrane is excellent in selective permeability and bio-compatibility, and expected to show its effect mainly in medical applications such as separation of plasma.
