PHOTO- AND/OR THERMO-CURABLE COPOLYMER, CURABLE RESIN COMPOSITIONS, AND CURED ARTICLES

摘要

A photo- and/or thermo-curable copolymer having polymerizable unsaturated groups in side chains, prepared from both a copolymer (P) comprising monomer units derived from a carboxyl-containing polymerizable unsaturated compound (A) and monomer units derived from at least one epoxy-containing polymerizable unsaturated compound (B) represented by the general formula (1) or (2) and an epoxy-containing polymerizable unsaturated compound (C) through addition reaction of part of the carboxyl groups of the copolymer (P) with the epoxy group of the compound (C) (wherein R^a's are each hydrogen or alkyl having 1 to 4 carbon atoms; and R^b's are each a single bond or C_1-12 alkylene which may contain a heteroatom). The curable copolymer exhibits excellent synthesis stability and storage stability and excellent curing characteristics and permits both epoxy crosslinking and radical crosslinking.
