MOLECULAR ORIENTATION ARTICLES MOLDED FROM HIGH-MOLECULAR WEIGHT POLYETHYLENE AND PROCESSES FOR PREPARING SAME

摘要

In accordance with the present invention, there are provided high molecular weight polyethylene molecular orientation molded articles formed from high molecular weight polyethylenes having a weight average molecular weight of 300,000-600,000, said molecular orientation molded articles having a fineness of not more than 15 deniers, a tensile strength of more than at least 1.7 GPa and satisfying the tensile strength S (GPa)-weight average molecular weight M. (g/mol)-fineness D (denier) relationship represented by the formula [I] $and\; processes\; for\; preparing\; the\; same.\; Further\; in\; accordance\; with\; the\; present\; invention,\; there\; are\; also\; provided\; high\; molecular\; weight\; polyethylene\; molecular\; orientation\; molded\; articles\; formed\; from\; high\; molecular\; weight\; polyethylene\; having\; a\; weight\; average\; molecular\; weight\; of\; exceeding\; 600,000\; and\; satisfying\; the\; relationship\; represented\; by\; the\; formula\; [II].$ $$
