CATALYST SYSTEM AND ITS USE IN OLEFIN POLYMERIZATION |
摘要 |
A polymerization catalyst system and a method for preparing the catalyst system is disclosed. The catalyst system includes a bulky ligand metallocene catalyst compound, preferably containing a single cyclopentadienyl or substituted cyclopentadienyl-type ring system, a Group 13 element containing first modifier, and a cycloalkadiene second modifier. The present invention also provides a process for polymerizing olefins(s) utilizing the catalyst systems described herein.
