Abstract

The invention discloses a graft-modified polymer of chlorinated polyether, which belongs to the field of polymer modification and aims at graft-modifying chlorinated polyether. The modified polymer includes a main chain and a graft Branch chain, the main chain is a chlorinated polyether polymer chain, the graft chain is terminated on the main chain by the graft monomer, and the graft monomer is an unsaturated silane monomer and an auxiliary graft A graft monomer, the auxiliary graft monomer contains a benzene ring and a carbon-carbon double bond, and the graft modified polymer is added with a photoinitiator during graft modification.

Description

technical field [0001] The invention relates to the field of graft modification, in particular to a graft-modified polymer of chlorinated polyether and a preparation method thereof. Background technique [0002] The basic principle of irradiation graft copolymerization is to use high-energy radiation to generate several active points on the polymer skeleton, and then successfully graft another vinyl monomer or homopolymer to these active points to produce branched chains. [0003] Chlorinated polyether, also known as polychlorinated polyether, has attracted much attention in engineering plastics because of its outstanding chemical graft corrosion resistance, and its corrosion resistance is second only to polytetrafluoroethylene. It is stable, has excellent electrical insulation performance and wear resistance, and has wide application prospects. [0004] However, the poor toughness of chlorinated polyether products limits its wide application to a certain extent. Conten...
