Abstract
Procedure for obtaining high molecular polyethylenes, usable as synthetic materials, by means of polymerization of ethylene in the presence of polymerization-exciting mixtures obtained from aluminum trialcohiles with compounds of the metals titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, thorium and uranium at any pressures and temperatures of -20º and above, according to patents numbers 218,486, 219,019 and 219,168, characterized in that instead of or in addition to the aluminum trialcohils, aluminum compounds of the general formula RA1X2, where R means hydrogen or a hydrocarbon radical, X any other substituent, including also hydrogen or a hydrocarbon radical, preferably compounds of the general formula R2A1X, especially dialcohil monohalogenides or alternatively diaryl-aluminum.
