PURPOSE:To safely and readily provide a porous plastic without using an organic solvent by kneading and injection-molding a water-soluble thermoplastic organic polymer and a water-insoluble organic polymer and subsequently bringing the molded product into contact with water. CONSTITUTION:(A) One kind or more of water-soluble thermoplastic organic polymers (e.g. polyethylene oxide) and (B) one kind or more of water-insoluble thermoplastic organic polymers (e.g. polystyrene) are kneaded and injection- molded to give an injection-molded product, which is immersed in water to elute the water-soluble organic solvent for providing a porous plastic without generating the cracks of the molded product. |
