发明名称 MICROPOROUS MEMBRANES FROM POLY (ETHER-ETHERKETONE) TYE POLYMERS AND LOW MELTING POINT CRYSTALLIZABLE POLYMERS AND A PROCESS FOR MAKING THE SAME
摘要 The invention relates to a process for preparing a microporous membrane from an unsulfonated poly(etheretherketone)-type polymer by forming a mixture of an unsulfonated poly(etheretherketone)-type polymer, a low melting point crystallizable polymer, and a plasticizer, heating the resulting mixture, extruding or casting the mixture into a membrane, quenching or coagulating the membrane, and leaching the membrane, while optionally drawing the membrane before, during, after leaching, or a combination thereof.
