PROCESS FOR THE POLYMERIZATION OF ETHYLENE AND A SMALL AMOUNT OF A DIENE

摘要

Disclosed is a polymerization process utilizing a low level of diene to control the polymer product's melt index ratio independently of the melt index and density. The process of the invention produces polymers with enhanced processability. More specifically the process produces ethylene based polymers, prepared in gas phase polymerization processes utilizing bulky ligand metallocene polymerization catalysts, having enhanced melt strength and shear-thinning behaviour.
