Abstract

PURPOSE:To prepare unsaturated polyester resins useful for molded products, capable of utilizing industrial wastes effectively, characterized by isolating residual compounds which yield when crude aromatic dicarboxylic acid solutions are purified to obtain the high-purity aromatic dicarboxylic acids, and using the said compounds as saturated carboxylic acids.
