Abstract

PURPOSE: To manufacture a porous resin molded article having excellent elasticity and low dimentional change by water- or oil-absorption, by dispersing a specific carbonate to a low-density polyethylene or a chlorinated polyethylene, molding the composition, and extracting the carbonate from the molded article with sulfuric acid or an organic acid.
CONSTITUTION: A low-density polyethylene or a chlorinated polyethylene is compounded with fine powder of a carbonate selected from Na2CO3, K2CO3, MgCO3 and NiCO3; a mixture of a solvent and a hydrophilic solvent such as ethylene glycol, propylene glycol, etc., is added to the mixture, the composition thus obtained is kneaded at 80W110°C to disperse the carbonate uniformly to the composition; and the composition is compression molded to a sheet. The sheet is immersed in a dilute sulfuric acid, sulfamic acid or an aqueous solution of an organic acid and heated at 40W60°C or irradiated with ultrasonic wave to extract the carbonate from the molded article. After extraction, the article is washed with water.
