A process for production of an ethylene-propylene-dime-methylene (EPDM) tetrapolymer having long chain branching is described. The process comprises the step of polymerizing a monomer mixture comprising ethylene, propylene, a first diolefin monomer containing one polymerizable double bond (preferably ENB) and a second diolefin containing two polymerizable double bonds (preferably VNB) in the presence of a catalyst system. The catalyst system comprises: a catalyst comprising a compound containing vanadium +3 with the proviso that the compound does not comprise a halogen directly bound to the vanadium; a halogenated organoaluminum cocatalyst having a halogen to aluminum molar ratio in the range of from about 1 to about 2; and an activator. The branched polymer product of the present process exhibits a molecular weight distribution of less than about 3.5 and improved rheological properties and enhanced processability characteristics.
