Abstract
Procedure for the manufacture of polyethylenes with a molecular weight of more than 500,000; and at temperatures ranging from 30 to 130ºC as well as pressures of one to 100 atmospheres, with the use of so-called Ziegler-type catalysts, which include titanium III halides as well as organic combinations of aluminum, this procedure which is characterized by the fact that catalysts are used in the first place, which are made up of both the titanium III halides and the organic compounds of aluminum mentioned in a molar ratio from 1 to 0.2 to 1 to 5 Drinking, in this case, the aforementioned Titanium III Halide has been prepared in a separate way, that, secondly, an ethylene whose oxygen content is less than 5 ppms is used, as well as that, thirdly, During the polymerization, an alcohol is added to the reaction mixture in amounts of two to ten mol, per kilogram of said catalyst.
