Abstract
Improvements introduced in the main patent no. 245,178, by: Process for the manufacture of polyolefins, especially of polyethylene with dihalogen-monoalkyl aluminum application, as metal-organic combinations, characterized in that, having dihalogen-monoalkyl-a-luminic present simultaneously, tri- and tetravalent titanium combinations (Ti '' ', Ti' '' ') in the catalyst for the polymerization imports the molecular ratio of dihalogenmonoalkyl aluminum: Ti' '': Ti " as 1: 0.5-2: 0.05-0.5, preferably 1: 0.75-1.5: 0.1-0.4.
