Abstract
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] ##EQU1## 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]. ##EQU2##
