Abstract

Abstract An advanced addition product containing hydroxyl groups is prepared from the reaction of specific mononuclear hydantoin glycidyl compounds with non-aromatic dicarboxylic acids of 9 to 44 carbon atoms and, optionally mono-carboxylic acids of 6 to 18 carbon atoms. The above advanced addition products are heat curable with suitable curing agents for hydroxyl containing materials to afford cured compositions exhibiting excellent weathering, color stability and chalking resistance.
