Abstract
Process for preparing an unsaturated polyester resin, characterized by comprising heating together: (a) an alkylene oxide; (b) a mixture of maleic anhydride and the anhydride of another dicarboxylic acid, said at least about 10 mole% maleic anhydride containing; and (c) about 10 to 50 mole% approximately based on (b) water or a dihydric or polyhydric alcohol promoter; the indicated heating is carried out at a temperature below about 180º C until the reaction mixture has an acid number of less than about 240 and then the reaction mixture is heated to a temperature of the order of 180 to 250º C until a product of a acidity index of approximately 60.
