Abstract

The invention relates to a manufacturing method of a functionalized polyolefin material. The functionalized polyolefin material is composed of an olefin comonomer and a flexible diene comonomer, wherein the alpha-olefin comonomer is composed of ethylene, propylene and 1-dodecene; and the flexible diene comonomer is composed of 7-methyl-1,6-octadiene, 1,4-hexadiene and 4-vinyl-1-cyclohexene. The technical scheme can enhance the strength of the functionalized polyolefin material on the premise of ensuring the elasticity.

Description

technical field [0001] The present invention belongs to the preparation of epoxidized and hydrocarbylated copolymers of α-olefins and dienes, especially the production of thermally stable oil-resistant elastomers by epoxidized and hydroxylated copolymers of flexible dienes. Background technique [0002] In the automotive and other fields, especially in the engine field, there are many places where oil-resistant and high-temperature-resistant elastomers are required. The currently used high temperature elastomers with oil resistance are mainly chloroprene and nitrile rubber, but the high temperature resistance of these two materials is insufficient. [0003] It has been proposed that the functionalized polyolefin (FPO) material prepared by epoxidized and alkylated copolymer of α-olefin and flexible diene not only surpasses chloroprene and nitrile rubber in terms of high temperature resistance, And it is also lower than the currently used chloroprene and nitrile rubber in ter...
