Titanium tetrachloride organoaluminium co-catalyst is used in which of the following polymerisation?

Titanium tetrachloride organoaluminium co-catalyst is used in which of the following polymerisation? Correct Answer Ziegler-Natta polymerization

Coordination polymerization with heterogeneous Ziegler-Natta catalysts is based on titanium tetrachloride and organo-aluminium co-catalyst. The mixing of TiCl4 with trialkylaluminium complexes produces Ti(III)-containing solids that catalyse the polymerization of ethylene and propylene.
