Abstract
A curable copolymer is provided wherein an unsaturated epoxy resin is prepared by reacting epoxy resin and acrylic and/or methacrylic acid, said unsaturated epoxy resin containing both a epoxy group and acryloyl and/or methacryloyl groups, with which a vinyl monomer is reacted in the presence of a radical catalyst to form an epoxy resin side chain. The resultant resin is finally reacted with acrylic and/or methacrylic acid to react with the remaining epoxy resin thereby resulting in terminal acryloyl and/or methacryloyl groups. This resin can be used as coating paint or molding resin or for a variety of other uses.
