Abstract: A synthetic fiber substantially comprising: (A) 5-40% by weight of a copolymer consisting of (a) 20-80% by weight of polyvinyl alcohol, and(b) 80-20% by weight of acrylonitrile, and(B) 60-95% by weight of a copolymer consisting of (c) 55-95% by weight of styrene, and(d) 5-45% by weight of acrylonitrile. This fiber is used for producing paper and has a potentially fibrillar texture. When beaten, it forms synthetic pulp having stalk fibrils and micro fibrils extending from the stalk fibrils. High-tenacity synthetic paper can be made because this synthetic pulp is self-adhesive.

Abstract: Provided is a porous fiber that is a solid fiber having a modified cross-sectional shape and that satisfies the following (a) and (b): (a) when, in a transverse cross section of the solid fiber, the diameter of an inscribed circle is Di and the diameter of a circumscribed circle is Do, a modified cross section degree Do/Di is 1.20-8.50; and (b) the specific surface area of the fiber pore is not less than 30 m2/g. Also provided is an absorbing material that contains not less than 28 vol% of the porous fiber as a fiber bundle. Also provided is a purifying column formed from: the absorbing material being arranged in a case axial direction and in a straight shape; and a plastic casing having both ends at which an inlet port and an outlet port for a liquid to be treated are provided. The present invention thus provides: the porous fiber that allows efficient absorption of a substance to be removed in the liquid to be treated; and the purifying column having the porous fiber embedded.

Abstract: Disclosed is a membrane material comprising a hydrophobic polymer and a hydrophilic polymer. The hydrophilic polymer consists of 10-50 wt.% of a low molecular weight component having a molecular weight of less than 100,000 and 90-50 wt.% of a high molecular weight component having a molecular weight of at least 100,000. The membrane material may be subjected to an insolubilization treatment to provide a permselective membrane suitable for use in dialysis. The membrane material may have an overall mass transfer coefficient (K o), for a Stokes' radius of at least 30 .ANG. (as determined by a diffusion test using dextran), of at least 0.0025 cm/min and a permeability to albumin of at most 4 %.

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.
