ABSTRACT:
Ethylene is polymerized through the use of an improved catalyst system consisting of a carrier such as neodymium oxide having a high superficial area, an aluminum compound such as triisobutylaluminum and the combination product of titanium trichloride and an isostructural chloride of another transition metal prepared by impregnating the carrier with a solution of a carbonyl derivative of the other transition metal, refluxing the impregnated carrier with titanium tetrachloride until that carbonyl derivative is converted to the chloride of the other transition metal, and then removing the excess of titanium tetrachloride.
