POLYPROPYLENE-BASED RESIN COMPOSITION HAVING EXCELLENT SCRATCH RESISTANCE AND MOLDING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To obtain a polypropylene-based composite material having an excellent rigidity and impact resistance while solving a phenomenon in which a talc-containing composite material causes whitening and makes a flaw conspicuous when damaged, namely a polypropylene-based resin composition and a molded article thereof. SOLUTION: The polypropylene-based resin composition comprises 100 pts.wt. of a polypropylene-based resin (A), 0.5-100 pts.wt. of an aluminum silicate mineral (B) and 0.1-20 pts.wt. of a polar group-containing polymer (C). The molded article thereof is obtained. COPYRIGHT: (C)2008,JPO&INPIT
