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:As a crystalline polypropylene resin, a propylene homopolymer or a propylene/ethylene random copolymer with ethylene content of up to 4wt.% is designated and the melt flow rate thereof is 5-80g/10min. Injection molding is performed using 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 crystalline polypropylene resin. By this method, a molded product improved in thermal deformation temp. to a large extent can be obtained and is useful for a container for a microwave oven. |
