polypropylene-based resin composition, method for producing a polypropylene-based resin molded article and polypropylene-based resin molded article

摘要

PROBLEM TO BE SOLVED: To provide a new polypropylene-based resin composition which hardly generates an odor and bleeding, when molded, is excellent in lightness, and is excellent in the flexural modulus and impact resistance of an obtained molded product.;SOLUTION: The polypropylene-based resin composition is produced by mixing isotactic polypropylene-based particles (A) having an average particle diameter of 100-2,000 μm with polar group-containing polypropylene-based particles (B) having a polar group content of 0.1-10 mol% and a propylene chain isotactic triad fraction of ≥90% measured with ¹³C-NMR so that the polar group-containing polypropylene-based particles (B) content is 0.001-10 mass%, and then melt-kneading the mixture.;COPYRIGHT: (C)2013,JPO&INPIT
