Abstract

The invention relates to a catalyst for norbornene, maleic anhydride and acrylic ester ternary polymerization and a preparation method of the catalyst and a ternary polymerization method; the catalyst is prepared by rare-earth complex and halogenated hydrocarbon and can generate catalytic activity in a nitrogen protection system at normal pressure and at the temperature of 0-150 DEG C for catalyzing norbornene, maleic anhydride and acrylic ester ternary polymerization, and the products are soaked by methanol for easy washing and separation; the invention has the characteristics of high copolymer yield, low reaction temperature, cheap and easy-obtaining catalyst and high catalyst efficiency.

Description

Technical field [0001] The present invention relates to the field of polymer synthesis, and specifically refers to a catalyst for the ternary copolymerization of norbornene, maleic anhydride and acrylate, a method for preparing the catalyst, and the use of the catalyst to carry out norbornene, maleic anhydride and acrylic acid The method of ester copolymerization. Background technique [0002] Polynorbornene is a special polymer with excellent mechanical properties, heat resistance, solubility and transparency in organic solvents, and can be used for 193nm UV lithography. The main disadvantages of this material are brittleness, poor viscosity and low molecular weight. After inserting maleic anhydride into the polynorbornene main chain, the adhesion and solubility of the polymer can be improved, and the polymerization of acrylate can increase the toughness of the copolymer photolithography material. This terpolymer can be used as a photoresist material for 193nm photocopying tec...
