Abstract
PURPOSE: To mold continuously uniform film having high mechanical strength and a high porosity, by molding a blend of polyolefin resin with a specific polyalkylene oxide and fine powder as matters to be extracted, and water- insoluble fine powder, followed by extracting the molded film.
CONSTITUTION: A composition obtained by blending 15W60vol% polyolefin resin, 3W40vol% polyalkylene oxide having a molecular weight of ≥4,000, a ratio of (the melt viscosity of its molding temperature)/(the melt viscosity of the resin) of <3 and 20W80wt% fine powder as matters to be extracted, 0.5W10wt% water-insoluble fine powder, is molded into a film by melt extrusion, only the polyalkylene oxide and the fine powder added as the matters to be extracted are extracted with a solvent, e.g., water, and removed. Pentaerythritol having an average particle diameter of ≤10μ is preferable as the matter of the fine powder to be extracted, and fine powder of hydrous silicic acid, etc. is preferable as the water-insoluble fine powder.
