Curable resin compositions and process for preparing oligomers and polymers having acryloyl groups, substituted methacrylate groups and beta-dicarbonyl groups

Abstract

A curable resin composition which exhibits no drawbacks such as yellowing and exhibits excellent hydrolysis sensitivity is provided, and a process for preparing curable oligomers and polymers which has foregoing properties is provided. The composition comprises a curable oligomer or polymer, wherein the oligomer or polymer has an acryloyl group, a β-dicarbonyl group having a chemical structure part represented by any of the following structures, 1 and a substituted methacrylate group represented by the following structure. 2 The process comprises a reaction step of reacting at least one multifunctional monomeric acrylate with at least one compound having at least one β-dicarbonyl group in the presence of a tertiary organic phosphine.
