Abstract

The invention provides an application and a usage of vanadium series catalyst of one-class bidentate N, O coordination. From the angle of preventing functional monomer from poisoning catalyst, the invention selects the vanadium series olefinic polymerization catalyst of one-class bidentate N, O coordination to realize the copolymerization of ethylene and polar monomer under the action of cocatalyst and promoter after different protecting agents pretreat the polar monomer. Through adjusting copolymerization conditions, the invention obtains a series of functional polyolefine with controllable comonomer insertion rate and molecular weight. Especially, the invention realizes the copolymerization between ethylene and 10-hendecene-1-alcohol, between ethylene and 5-hexene-1-alcohol, between ethylene and 3-butylene-1-alcohol or between ethylene and 10-methyl undecylenate.

Description

technical field [0001] The invention relates to the use and usage of a class of bidentate N, O coordinated vanadium catalysts, in particular to a class of bidentate N, O coordinated vanadium catalysts to realize copolymerization of ethylene and polar monomers and a method thereof. Background technique [0002] Polyolefin products are widely used in various fields, bringing revolutionary changes to people's lives. However, the low surface energy of polyolefins and the chemical inertness of the molecules make the functional properties of polyolefins (adhesion, wettability, printing and dyeing properties, gas permeability, and compatibility with other substances, etc.) poor, and it is difficult to meet Demand for ever-increasing properties of polyolefin materials. Therefore, the functionalization of polyolefin materials has been paid more and more attention by people. [0003] A lot of research has been done abroad on the functionalization of polyolefins, and progress has bee...
