摘要： PROBLEM TO BE SOLVED: To obtain a polyolefin resin composition excellent in the balance between the rigidity and the impact resistance of an injection molded article, coatability, moldability, appearance, etc., by compounding a specified propylene/ethylene block copolymer and a specified talc each in a specified amount. SOLUTION: This resin composition consists of 70-95wt.% highly rigid propylene/ ethylene block copolymer comprising a propylene/ethylene block copolymer which is obtained in the presence of a specified catalyst by polymerizing propylene alone in the first polymerization step (A) using two or more polymerizers in series to produce a propylene homopolymer accounting for 60-95wt.% of the total weight of the block copolymer and copolymerizing propylene and ethylene in the second polymerization step (B) using one or more polymerizers to produce a propylene/ethylene copolymer part having an ethylene content of 30-80wt.% and accounting for 5-40wt.% of the total weight of the block copolymer and in which the ratio of the maximum value of MFR's of polymers obtained in the polymerizers in the step A to the minimum value thereof, the isotactic pentad fraction, the Mw/Mn (Q value) and the ratio of MFR of the polymer obtained in the step A to that in the step B are each a specified value; and 5-30wt.% talc with a mean particle diameter of 5μm or smaller.
