Catalyst Formulation and Polymerization Processes Abstract Methods of polymerization of unsaturated hydrocarbons over Ziegler-type catalysts, and processes for formulating such catalysts consist of sequentially mixing the various components thereof and controlling the order of addition and the durations of mixing such catalyst components. The catalyst components utilized involve a transition metal component, an electron donor component, specifically an organosilicon external electron donor, and a co-catalyst component, specifically, an organoaluminum co-catalyst, which are sequentially mixed together in the course of formulating the Ziegler-type catalyst to be charged to an olefin polymerization reactor.
