Abstract

PURPOSE:To obtain a high-strength high-modulus polyethylene molding excellent in creep resistance, by blending two specified ultrahigh-MW polyethylenes, dispersing the blend in a solvent, molding the dispersion into a fiber and drawing this fiber under heating. CONSTITUTION:An ultrahigh-MW polyethylene (A) having a viscosity-average MW >=500,000 and less than two branches per 1,000 carbon atoms of the main chain is blended with an ultrahigh-MW polyethylene (B) having a viscosity- average MW >=500,000 and at least four branches per 1,000 carbon atoms of the main chain. The obtained blend is dispersed in a solvent, spun or extruded and cooled to a temperature lower than the dissolution temperature. The obtained polymer gel is drawing under heating to obtain the title molding of a tensile strength >=25g/d, a tensile modulus >=800g/d and a creep rate (as measured at 50 deg.C under a load of 9g/d) <=3X10<-7>/sec.
