摘要： A polyarylate comprising units derived from an aromatic carboxylic acid compound and units derived from a bisphenol compound and containing an epoxy group. According to the process of the present invention, the polyarylate having epoxy group can be economically prepared. Since the polyarylate of the present invention has epoxy group, it has the reactivity with amino group, hydroxyl group, acid anhydride group, or the like. Therefore, the polyarylate is mixed with another polymer to give a polymer alloy or is utilized as the precursor of a graft-copolymer, utilizing the reactivity.
