摘要: Polypropylene interior parts for autocars having overcome the drawback of their permanent bulge or secondary deformation due to high temperature exposure is provided, which parts are obtained by molding a material comprising a propylene-ethylene block copolymer prepared by polymerizing propylene at a first stage so that the resulting propylene homopolymer can have a relation between its isotactic pentad ratio (P) and MFR of1.00.gtoreq.P.gtoreq.0.015 log MFR+0.955and can occupy 70 to 95% by weight of the total polymerization quantity, followed by polymerizing ethylene or ethylene and propylene in 30 to 5% by weight of the total polymerization quantity at at least one stage, so as to give an ethylene content occupying 3 to 12% by weight of the total polymerization quantity.
