PURPOSE:To obtain a polypropylene resin molded product excellent in heat resistance by the injection molding of a compsn. consisting of a crystalline polypropylene resin prescribed in melt flow rate and ethylene content and a specific amt. of an aliphatic, alicyclic or aromatic dibasic acid type diamide compd. CONSTITUTION:A propylene/ethylene block copolymer to be used contains 2-15wt.% of ethylene and has a melt flow rate of 1-80g/10min. A compsn. prepared by adding 0.005-5 pts.wt. of an aliphatic, alicyclic or aromatic dibasic acid type diamide compd. to 100 pts.wt. of the block copolymer is subjected to injection molding. By this method, a molded product high in thermal deformation temp. and impact strength at the normal temp. and low temp. can be obtained. |
