MICROPOROUS FILM OF SEMICRYSTALLINE POLYMER AND METHOD FOR PREPARING THE SAME
摘要
<p>Microporous films of the semicrystalline polymer according to the present invention are obtained by stretching semicrystalline polymer sheets extruded through a die with the phase separation between a semicrystalline polymer resin and a diluent, of which sheet is comprised of a crystalline region, a pore region, and a non-crystalline region which is a swollen region swollen by the diluent, and extracting the diluent.</p>
