Abstract
PURPOSE: To improve the hydrophilic nature of the titled semipermeable membrane and to obtain the membrane of good heat resistance and chemical resistance and a high rate of water permeation by producing a polysulfone semipermeable membrane by the use of a high polymer material soln. prepd. by mixing a cellulose deriv. with an aromatic polysulfone.
CONSTITUTION: A mixer of an aromatic polysulfone and a cellulose deriv. of 99/1W 40/60 weight mixing ratios is dissolved in an org. solvent (dimethyl formamide, dimethylacetamide, etc.) in such a way that it is contained at 10W30w% basing on the weight of the raw liquid, after which it is molded by a wet or dry and wet type method. If polyvinyl pyrolidone is added into the filming raw liquid at 1W20w% basing on the weight of the raw liquid as a compatibilizing agent, the compatibility of the polysulfone and the cellulose deriv. is improved.
