Abstract
An olefin (co-)polymer composition including 0.01 to 5.0 weight parts of high molecular weight polyethylene which is an ethylene homopolymer or an ethylene-olefin copolymer containing 50 weight % or more of an ethylene polymerization unit; and 100 weight parts of an olefin (co-)polymer other than the high molecular weight polyethylene, wherein said high molecular weight polyethylene has an intrinsic viscosity [.eta..sub.E ] of 15 to 100 dl/g measured in tetralin at 135.degree. C. or more, and said high molecular weight polyethylene exists as dispersed fine particles having a numerical average particle size of 1 to 5000 nm.
