POLYPROPYLENE RESIN COMPOSITION AND ITS MOLDING

摘要

PROBLEM TO BE SOLVED: To obtain a polypropylene resin composition having lightweight, excellent mechanical strength and improved impact resistance and its molding. SOLUTION: The polypropylene resin composition comprises 100 parts wt. of a resin composition composed of 50-95 wt.% of a polypropylene (A) containing a polypropylene (X) modified with a hydroxy group-containing vinyl monomer (G) and 5-50 wt.% of a polycarbonate (B) and 5-40 parts wt. of an elastomer component (C) containing an ethylene-α-olefin copolymer composed of ethylene and a≥4Cα-olefin. Preferably 0.1-50 wt.% of the polypropylene (X) modified with the hydroxy group-containing vinyl monomer (G) is contained in the polypropylene (A). COPYRIGHT: (C)2005,JPO&NCIPI
