Ziegler-natta catalyst for narrow to broad MWD of polyoefins, method of making, method of using, and polyolefins made therewith

   
   

A new synthesis of a Ziegler-Natta catalyst uses a multi-step preparation that includes treating a magnesium dialkoxide compound with halogenating/titanating agents, and an organoaluminum preactivating agent. The catalyst may be used in the polymerization of olefins, particularly ethylene, to control the molecular weight distribution and the fluff morphology of the resulting polyolefins.
