Abstract

PURPOSE: To obtain hydrophilic plastic molded article which has good durability and constantly exhibits good performance over a long period of time, by a method wherein PVA solution is penetrated into the pores of a porous plastic molded article, PVA is coagulated and then the molded article is heat-treated to fix PVA.
CONSTITUTION: A porous plastic molded article is coated with a solution of polyvinyl alcohol having a polymn. degree of not less than 500 to penetrate part of the solution into the pores of the porous plastic molded article. Then the porous plastic molded article is immersed in a coagulating bath to coagulate polyvinyl alcohol. The molded article is heat-treated to fix polyvinyl alcohol on the porous plastic molded article. When hydrophilic powder is previously fixed in the pores of the porous plastic molded article or on the surface thereof and the resulting molded article is used, a hydrophilic molded article to which further more hydrophilic nature is imparted can be obtd.
