Abstract
PURPOSE: To a waste liquor containing maleic acid are added dicylopentadiene and specific solvent and then water is distilled off azeotropically therefrom to conduct esterification. Thus, the waste liquor containing maleic acid can be utilized as a component of an unsaturated polyester resin.
