POLYPROPYLENE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a polypropylene resin composition which gives a molded article excellent in external appearance, e.g. having few flow marks exhibiting a high die swell, and having few granular structures and to provide the molded article prepared from the same. SOLUTION: This resin composition has a melt flow rate(MFR) of 5.0-150 g/10 min and comprises (A) 95-50 wt.% propylene homopolymer having an intrinsic viscosity [η]A of 1.3 dl/g or lower and (B) 5-50 wt.% propylene-ethylene block copolymer which has a propylene homopolymer part having an intrinsic viscosity [η]BP of 1.4-2.0 dl/g and a propylene-ethylene random copolymer part having an intrinsic viscosity [η]BEP of 4.0-15 dl/g and is produced by gas-phase continuous polymerization. The molded article is prepared from the resin composition.
