Abstract

PURPOSE: A propylene polymer composition improved in adhesion of a paint while keeping excellent mechanical strength, which is prepared by compounding a crystalline propylene polymer with a specified rubber and a fine calcium carbonate particle.
CONSTITUTION: A composition comprising 40W85wt% crystalline propylene polymer (A), 3W30wt% at least one rubber (B) selected from an ethylene-propylene copolymer rubber, polyisoprene rubber and isobutylene-isoprene copolymer rubber, and 5W30wt% precipitated or wet-crushed heavy calcium carbonate (C) of average particle size 0.05W1.0μ in a wt% ratio of (B+C):(A+B+C) of (15W60):100. The crystalline propylene polymer is a propylene homopolymer, a block or random copolymer of propylene with another α-olefin pref. an 8C or lower α-olefin contg. 20wt% or less said olefin, or the like.
