| titleOfInvention | Production of microporous film |
| abstract | PURPOSE:To obtain the title film having a large gas flux and excellent mechanical strengths, by infiltrating a crystallization promoting solvent into a molding of a crystalline polymer of a crystallinity <= a specified value and forming micropores in this molding. CONSTITUTION:A crystalline polymer molding comprising a polyolefin, polyester, polyamide, vinyl, polyurethane or like polymer and having a form of film, tube, hollow fiber or the like is immersed in a solvent which promotes the crystallization of the crystalline polymer and can swell the molding to a degree of swelling >=1.2 for 5min-2hr to infiltrate the solvent into the molding and to make the molding porous. This molding is optionally stretched at a draw ratio of 1.5-15 to obtain the title film composed of particulate aggregate of particles of a mean diameter of 0.1-10mu and a network structure formed of fibrils of an average width of 0.01-5mu and an average length of 0.5-50mu. |
