Abstract
A process for obtaining mixtures of normally solid ethylene polymers with improved density, resistance to bending and tearing, yield strength and ease of processing, containing an ethylene homopolymer and 10 to 90% by weight of an ethylene homopolymer. -polyethylenepropane, with a drawing speed of at least 15 meters/minute, which includes the step comprising heating ethylene at a temperature between 140 and 250ยบ C and at a pressure between 800 and 2000 atmospheres in the presence of an ethylene polymerization catalyst capable of producing free radicals and from 2 to 20% by weight of propane with respect to the weight of ethylene.
