Abstract: Disclosed herein are film, fiber, molding composition and molded article including copolyesters that exhibit improved heat-resistance and thermo-mechanical stability. The copolyester is derived from an aliphatic glycol, an aromatic dicarboxylic acid selected from naphthalene dicarboxylic acid and terephthalic acid, and 5-50 mol % (based on 100 mole % of all glycols) of an additional monomer, bis(2-hydroxyalkyl)-2,2′-(1,4-phenylene)bis(1,3-dioxoisoindoline-5-carboxylate). The aromatic dicarboxylic acid is at least one of naphthalene dicarboxylic acid and terephthalic acid and the aliphatic glycol is selected from C2, C3 or C4 aliphatic diols. Furthermore, the copolyesters have crystallinity of at least 10%.
