Abstract
Improvements introduced in the object of the main patent no. 353,811, granted on december 18, 1968, by: "continuous procedure for the polymerization of ethylene", in which it is polymerized at a temperature not lower than 125ºc and at a pressure not inferior at 500 atmospheres, using a ziegler-type catalyst, characterized in that said catalyst comprises a combination of an organoaluminic activator and a trivalent titanium component, wherein said trivalent titanium component has been finely dispersed using it, alone or together with organo-aluminum activators, added, as a catalyst for the preparation of a minor proportion of an amorphous polymer.
