Polyolefin resin composition and molded article containing the same

摘要

There is provided a polyolefin resin composition capable of affording molded articles being superior in tensile elongation at break and impact resistance. The composition includes not less than 1 wt % and less than 80 wt % of a propylene polymer (I) that is a propylene homopolymer or a copolymer of propylene and at least one comonomer, the copolymer having more than 0 wt % and less than 20 wt % of structural units derived from the at least one comonomer, not less than 1 wt % and less than 80 wt % of a propylene copolymer (II) having 20 to 80 wt % of structural units derived from the comonomer and/or an ethylene copolymer (III) having a density of less than 940 kg/m3, and more than 20 wt % and not more than 98 wt % of an ethylene polymer (IV) having an MFR of 12 to 100 g/10 minutes and a density of 940 to 970 kg/m3.
