Abstract

Process for the preparation of an improved catalyst intended for the polymerization of defines which consists in activating a chromium oxide catalyst with support at a temperature comprised between 260 and 1093º c. (500 and 2000º f), and then contacting the catalyst thus activated with a hydrocarbyl-hydrocarbyl-aluminum oxide, characterized park said contact is carried out at a temperature below 27º c. (80ºf).
