Propylene resin composition

摘要

There is provided a propylene resin composition consisting essentially of the following components (a) and (b): component (a): 100 parts by weight of a propyleneethylene block copolymer composed of 60 to 80% by weight of crystalline polypropylene homopolymer moiety (unit A moiety), and 20 to 40% by weight of ethylene-propylene random copolymer moiety (unit B moiety) having an ethylene content of 30 to 60% by weight and a weight-average molecular weight (Mw) of 200,000 to 400,000, the melt flow rate of the component (a) being from 25 to 100g/10 min; and component (b): 1 to 60 parts by weight of an ethylene- alpha -olefin copolymer rubber containing 20 to 50% by weight of an alpha -olefin having 3 to 16 carbon atoms.
