Title:
PROCESS FOR PRODUCING MICROPOROUS POLYOLEFIN FILM AND MICROPOROUS POLYOLEFIN FILM
Document Type and Number:
WIPO Patent Application WO/2006/104165
Kind Code:
A1
Abstract:
The microporous polyolefin film produced by drawing a gel molding containing a polyolefin and a solvent for film formation in at least a uniaxial direction, removing the solvent for film formation and once more drawing the molding at a rate of ≥ 3 %/sec in at least a uniaxial direction at temperature of ≤ polyolefin crystal dispersion temperature + 20°C is excellent in compression resistance.
