Title:
OLEFIN POLYMERIZATION METALLOCENE CATALYST COMPOSITION, PREPARATION THEREOF AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/246009
Kind Code:
A1
Abstract:
An olefin polymerization catalyst composition, comprising a main catalyst and a carrier. The carrier is fluorinated silica gel particles, and the main catalyst is a metallocene complex represented by general formula (I). Also disclosed are the preparation of the composition and use of the composition in olefin polymerization reactions. The composition provided by the present invention can reduce or avoid the use of methylaluminoxane or borate reagents while improving polymer morphology.
