PURPOSE:To obtain the titled resin useful for various uses such as building materials, etc., having excellent impact resistance and heat resistance, by esterifying an acid anhydride group of a specific copolymer with a specific hydroxy compound and then reacting the resultant compound with an epoxy compound. CONSTITUTION:An acid anhydride group of a copolymer consisting of an alpha,beta-unsaturated acid anhydride (e.g. maleic anhydride, citraconic anhydride, etc.), a vinyl compound (e.g. styrene, acrylonitrile, etc.) copolymerizable with the acid anhydride and a 1,3-diene compound (e.g. 1,3-butadiene, etc.) is esterified with a compound having the same structural formula of a hydroxyl compound prepared by reacting an epoxy compound shown by the formula X and Y are H, CH3, etc.) with (meth)acrylic acid, an unsaturated double bond is introduced to the side chain of the copolymer and the acid anhydride group of the copolymer is subjected to ring opening to form carboxyl group. A part to the whole of the formed carboxyl group is reacted with the epoxy compound shown by the formula to give the aimed resin.
