POLYPROPYLENE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a polypropylene composition excellent in rigidity and impact resistance, high in shrinkage rate in molding and improved in fluidity. SOLUTION: This polypropylene composition comprises 35-95wt.% of a polypropylene having 5-400g/10 minutes melt flow rate (measured at 230 deg.C), 5-50wt.% of an ethylene/ a-olefin random copolymer having 0.01-10g/10 minutes melt flow rate (measured at 230 deg.C) and 2.5×10<6> to 1.0×10<7> poise viscoelasticityη*(measured at 200 deg.C at co :100' rad/second) and 0-25 wt.% an inorganic filler. The viscoelasticity valueη* of the ethylene/α-olefin random copolymer (measured at 200 deg.C atω=10 rad/second) is preferably 1×10<4> to 3×10<5> poise.
