PURPOSE:To obtain the titled composition outstanding in both wear and impact resistances, easy to form, by incorporating ultra high molecular weight polyethylene with a polymer giving anisotropic molten state. CONSTITUTION:The objective composition can be obtained by incorporating (A) 100pts.wt. of ultra high molecular weight polyethylene with an average molecular weight of >=1,000,000 with (B) pref. 5-20pts.wt. of a polymer giving anisotropic molten state (e.g. a copolymer from polyethylene terephthalate and p-hydroxybenzoic acid). |
