PROCESS FOR PRODUCING POROUS LAMINATE AND POROUS LAMINATE |
摘要 |
<p>A process for producing a porous laminate having many micropores interconnected in the thickness direction, which comprises: a step in which a laminate is produced which comprises at least three layers comprising an interlayer made of a thermoplastic resin having a hard segment and a soft segment and two nonporous outer layers made of a filler-containing resin and located as outer layers respectively on both sides of the interlayer; a step in which the laminate obtained is impregnated with a supercritical or subcritical fluid and this state is relieved to vaporize the fluid and thereby make the interlayer porous; and a step in which the two nonporous outer layers located respectively on both sides are made porous by stretching.</p> |
