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 carbonyl compound. The invention is also directed to the use of the catalyst composition in the polymerization of olefin(s). In particular, the polymerization catalyst system is supported on a carrier. More particularly, the polymerization catalyst comprises a bulky ligand metallocene-type catalyst system.
