Homogeneous olefin polymerization catalyst composition

摘要

The present invention relates to an olefin polymerization catalyst composition comprising a metallocene and an aluminoxane containing alkyl groups with at least two (2) carbon atoms which provides more uniformity than methylaluminoxane, offers greater control and reproducibility of olefin polymerization and greater storage stability. The present invention also provides a method for the preparation of the olefin polymerization catalyst composition.
