Abstract
The present invention provides modified olefin polymerization catalyst, preparation method thereof, olefin polymerization catalyst system, use thereof and method of preparing polyolefin resin. The catalyst comprises an olefin polymerization catalyst and an organosilane, which is represented by a general formula RSiX(OR), where Ris a C-Calkyl group and a terminal of Rhas an α-olefin double bond, a norbornene group, a cycloolefin group or a dicyclopentadiene group, X is a halogen element, Ris a C-Clinear chain, branched chain or isomerized alkyl group, m is an integer from 1-3, n is an integer from 1-3, k is an integer within a range of 0-2, and m+n+k=4. High-performance polyolefin resins, including homopolymerized polyolefin resin with high melt and mechanical strength, polyolefin elastomer with high rubber phase content, and polyolefin elastomer with a rubber phase in a crosslinked structure, etc., can be obtained through polymerization with the catalyst.
