PURPOSE: A resin composition excellent in low-temperature resistance, etc., and suitable for use in car interiors, obtained by blending an ethylene-propylene copolymer rubber with a propylene-ethylene random copolymer and a propylene- ethylene block copolymer.
CONSTITUTION: The purpose polyolefin resin composition is prepared by blending (A) 40W80wt% ethylene-propylene copolymer rubber of a propylene content of 20W40wt% with (B) 15W50wt% propyelene-ethylene random copolymer of an ethylene content of 3W10wt% and (C) 5W25wt% propylene-ethylene block copolymer of an ethylene content of 5W30wt%. The resulting resin composition contains no plasticizer, so that when the composition is used to form a trim leather material for car interiors, sun-visor leather material, seat leather material or the like, any problem such as fogging, bleed, chalking, etc., does not occur.
