发明名称 PROPYLENIC RESIN COMPOSITION FOR INJECTION MOLDING, AND INJECTION-MOLDED ARTICLE THEREFROM
摘要 <P>PROBLEM TO BE SOLVED: To provide a propylene resin composition for injection molding, having excellent moldability and transparency and suppressed stickiness and to provide an injection molded article produced by using the composition. Ž<P>SOLUTION: The propylene resin composition for injection molding is prepared by using a propylene resin mixture having a melt flow rate (MFR) of 2.0-200 g/10 min measured at 230°C under a load of 2.16 kg and an ethylene content of 0.5-6.0 wt.% and comprising 50-99 wt.% of a high-molecular-weight ethylene-propylene random copolymer (A) having a weight-average molecular weight (Mw) of 140,000-380,000 and polymerized by using a metallocene catalyst and 1-50 wt.% of an ultra-low molecular weight ethylene-propylene random copolymer (B) having a weight-average molecular weight (Mw) of 29,000-120,000 and having been polymerized by using a metallocene catalyst.
