ABSTRACT:
A process for the homo- or co-polymerization of olefins by the low pressure method, using a catalyst comprising the combination of an organo-metallic compound of a metal of Group I, II or III of the Periodic Table of the Elements and a compound of a transition metal of Group IV, V or VI of said Periodic Table supported on a carrier. The carrier is a mixture of anhydrous MgCl.sub.2 with an alkoxy- or alkoxy-chloro-titanate in a MgCl.sub.2 /titanate molar ratio of from 0.01 to 1:1.
