    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 olefin(s) utilizing the catalyst systems described herein.
