Diester structure monomer, preparation method therefor, and application thereof

Abstract

The preparation method for the diester structure monomer includes the following steps: dissolving glycolate in a reaction solvent to prepare a glycolate solution; mixing the glycolate solution with triethylamine in a protective atmosphere, and cooling to form a mixture; and keeping the protective atmosphere unchanged, and adding the methacryloyl chloride to the mixture for esterification to generate a diester structure monomer. The diester structure monomer generated by the preparation method for the diester structure monomer has a long diester side chain and a group with a small volume and high acid sensitivity. As a result, a resin synthesized from the diester structure monomer has good adhesive force and film-forming property, high deprotection efficiency and plasticity, and the hardness and brittleness of the resin are improved. Moreover, the prepared diester acid protected structure monomer has the advantages of high yield, low by-product content and easy separation and purification.
