A process for producing polyethylene materials is disclosed in which particulate polyethylene is drawn at lower temperatures than its melting point, the polymer having an intrinsic viscosity of 5-50 dl/g at 135 DEG C. in decalin and resulting from the polymerization of ethylene at temperatures below the above melting point and with use of a selected catalyst. The polyethylene materials excel in mechanical strength and elastic modulus. |
