Title:
HYBRID CATALYST COMPOSITION, CATALYST COMPRISING SAME, AND METHODS FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2021/210835
Kind Code:
A1
Abstract:
The present invention relates to a hybrid catalyst composition comprising different transition metal compounds, a catalyst for olefin polymerization comprising same, and methods for preparing the hybrid catalyst composition and the catalyst. Particularly, the present invention relates to a hybrid catalyst composition, a catalyst for olefin polymerization comprising same, and methods for preparing the corresponding hybrid catalyst composition and catalyst, the hybrid catalyst composition comprising two or more transition metal compounds which have different core metals and non-bridged asymmetric biscyclopentadienyl groups.
