<；P>；PROBLEM TO BE SOLVED: To obtain a thick porous synthetic resin without being contaminated with impurities such as a surfactant, when the porous synthetic resin is produced by mixing the synthetic resin with water-soluble particulates in a process for molding the synthetic resin, curing the resin and then dissolving out the particulates. <；P>；SOLUTION: The method for producing the porous synthetic resin, comprising mixing a monomer or prepolymer, a reaction initiator for initiating the polymerization reactions, and water-soluble particulates, curing the mixture liquid, and then exposing the cured synthetic resin to water to dissolve out the particulates, is characterized by mixing the mixture liquid with water in an amount not dissolving the crystals. <；P>；COPYRIGHT: (C)2011,JPO&INPIT
