Abstract
Provided are use of organosilane, and polyolefin resin and preparation method thereof. The method of preparing the polyolefin resin comprises: conducting olefin polymerization of olefin monomers in the presence of a catalyst, and adding organosilane to a polymerization system before the olefin polymerization and/or during the olefin polymerization, wherein the organosilane is represented by a general formula of RSiX(OR), wherein Ris a C-Calkyl, and a terminal of Rhas an α-olefin double bond, a norbornene group, a cycloalkene group, or a dicyclopentadiene group; X is a halogen element; Ris a C-Cstraight chain, a C-Cbranched chain, or an isomerized alkyl group; m is an integer from 1-3; n is an integer from 1-3; k is an integer from 0-2; and m, n, and k satisfy the following condition: m+n+k=4. The polyolefin resin obtained by the above method has higher melt strength and mechanical strength.
