Abstract

Improvements in the object of the main patent no. 271,491, by "A PROCEDURE FOR PREPARING LINEAR LOTION COPOLYMERS AND ELEVATED MOLECULAR WEIGHT OF ETHYLENE AND ALPHA-OLEFINS", in the presence of a catalyst obtained by mixing a vanadium compound soluble in hydrocarbons and a dialkyl aluminum halide or a monoalkyl aluminum dihalide or an aluminum alkyl sesquihalide, characterized in that the vanadium compounds are chosen from the vanadium halides soluble in the hydrocarbons and the preparation of the catalyst and the The polymerization is carried out at a temperature between -10 and -50º C.
