Abstract
Provided are use of organosilane, in-reactor polyolefin alloy and preparation method thereof. The method of preparing an in-reactor polyolefin alloy comprises: conducting the first polymerization reaction of the first olefin monomer in the presence of a catalyst, and then charging the second olefin monomer into the polymerization reaction system to perform the second polymerization reaction, wherein the first olefin monomer is different from the second olefin monomer, wherein the first polymerization reaction and/or the second polymerization reaction are/is executed in the presence of organosilane represented by a general formula RSiX(OR), wherein Ris a C-Calkyl; 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 in-reactor polyolefin alloy obtained by the above method has a high degree of crosslinking in a rubber phase, high impact resistance, and low tensile strength at break.
