A CATALYST COMPOSITION AND METHODS FOR ITS PREPARATION AND USE IN A POLYMERIZATION PROCESS

摘要

The present invention relates to a catalyst composition and a method for making the catalyst composition of a polymerization catalyst and a carboxylate metal salt. The invention is also directed to the use of t he catalyst composition in the polymerization of olefin(s). In particular, the polymerization catalyst system is supported on a carrier. Mo re particularly, the polymerization catalyst comprises a bulky ligand metallocene-type catalyst system.
