Abstract

PURPOSE: Polymer composition, improved in the balance of rigidity, impact resistance and mar resistance, which comprises an olefin polymer, and talc and calcium carbonate having specified specific surface area.
CONSTITUTION: A composition comprising an olefin polymer, talc having specific surface area of ≥20,000cm2/g and calcium carbonate having that of ≥30,000cm2/g, the tolal amount of said talc and calcium carbonate being 20W50wt% based on said composition and the ratio of specific surface area of said talc to that of said calcium carbonate being 0.35W1.50. The talc used is produced by crushing the raw talc stone by a centrifugal roller mill, if required pulverizing it by a pulverizer, and classifying it by a wind classifier. The calcium carbonate used is synthesized by feeding quick lime resulting from the calcination of lime stone into water to form a slaked lime slurry and blowing carbon dioxide into the slurry.
