Abstract:
An olefin (co-)polymer composition comprising: 0.01 to 5.0 weight parts of a high molecular weight polyethylene which is an ethylene homopolymer or an ethylene-.alpha.-olefin copolymer containing 50 weight % or more of ethylene units; and 100 weight parts of a polypropylene which is a polypropylene homopolymer or a copolymer of propylene with at least one of ethylene or .alpha.-olefins having 4-12 carbon atoms containing 50 weight % or more of propylene units,wherein said high molecular weight polyethylene has an intrinsic viscosity (.eta..sub.E) of 15 to 100 dl/g measured in tetrahydronaphthalene at 135.degree. C. and said high molecular weight polyethylene exists as dispersed fine particles having a numerical average particle size of 10 to 500 nm.
