PROBLEM TO BE SOLVED: To provide a polypropylene resin composition having excellent heat-resistance, Rockwell hardness and ductility and an injection molded article made of the resin composition. SOLUTION: The polypropylene resin composition contains 100 pts.wt. of a resin mixture containing 86-95 wt.% propylene homopolymer or propylene copolymer having a melt flow rate of 2-90 g/10 min and 5-14 wt.% copolymer of ethylene and an olefin selected from propylene andα-olefin and having a density of 0.885-0.850 g/cm<SP>3</SP>and a melt flow rate of 1-50 g/10 min, and 0.03-2 pts.wt. of a nucleation agent. The invention further provides an injection molded article of the resin composition. COPYRIGHT: (C)2007,JPO&INPIT |
