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 of such fibers because this synthetic pulp is self-adhesive.

Abstract: Disclosed are hemodialysis membrane and hemodialysis method. The membrane has a total protein permeability of not more than 0.2%, and has a reduction rate of .beta.2-microglobulin of not less than 5%. The hemodialysis membrane selectively removes .beta.2microglobulin which was shown to cause some long-term complications such as carpal tunnel syndrome in the patients undergoing hemodialysis, while preventing the leakage of useful proteins.

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.
