Abstract

The invention belongs to the technical field of chemical catalyst, particularly relates to a metal olefin polymerization catalyst containing 8-hydroxyquinoline imine ligand and a preparation method thereof. The expression formula of the catalyst is MLCl3 or CP'MLCl2, wherein L represents tridentate anionic ligand which contains N and O atoms and is capable of coordinating with metals. The catalyst has a peculiar and novel structure and has high catalysis activity on catalytic vinyl polymerization, and is simple to prepare; a component A and a component B methylaluminoxane or modified methylaluminoxane of the catalyst are matched to be used for the catalyticvinyl polymerization reaction so as to prepare high molecular weight polyethylene product.

Description

Metal olefin polymerization catalyst containing 8-hydroxyquinoline imine ligand and preparation method thereof technical field The invention belongs to the technical field of chemical catalysts, and in particular relates to an 8-hydroxyquinoline imine ligand metal olefin polymerization catalyst and a preparation method thereof. technical background The polymer material industry is one of the main pillar industries of my country's national economy, closely related to people's daily life, and polyolefin accounts for about 35% of the total polymer material. Polyolefin is the pillar industry of modern polymer material industry, and olefin polymerization catalyst is the core of polyolefin industry. Because organometallic olefin polymerization catalysts can not only efficiently catalyze olefin polymerization under mild conditions, but also can tailor the microstructure of polymers, it is possible to design new functional polyolefin materials and improve the performance of existi...
