Abstract

The invention relates to oligomer epoxy resins which are derived especially from diphenols or from diglycidyl ethers based on these phenols, oligomer epoxy resins containing oxazolidinone groups and based on the novel diglycidyl ethers and curable mixtures containing the novel oligomer epoxy resins, and the reaction products of the novel oligomer epoxy resins with unsaturated carboxylic acids, preferably in the presence of a vinyl monomer to give phenacrylate resins, and phenacrylate resins containing oxazolidinone groups and based on the novel diglycidyl ethers.
