Polyester condensates of aromatic dicarboxylic acids and diphenols containing 1,2-bis(hydroxyphenyl)ethane in which the hydroxyl is in the 3 or 4 position. The component acids are selected from the group consisting of isophthalic acid, terephthalic acid, 3,3'-, 3,4'- and 4,4'-bibenzoic acids, 1,3-, 1,4-, 1,5-, 1,6-, 1,7-, 1,8-, 2,6-, and 2,7-naphthalenedicarboxylic acids and acids represented by the formula: ##STR1## wherein the carboxyl groups are in the 3- or 4- positions, and X is O, S, SO.sub.2, C.dbd.O, CH.sub.2, CH.sub.2 CH.sub.2, CH(CH.sub.3) or C(CH.sub.3).sub.2. The diphenol comprises 1,2-bis(hydroxyphenyl)ethane and optionally a diphenol selected from the group consisting of resorcinol, hydroquinone, 3,3'-, 3,4'- and 4,4'-diphenols, 1,3-, 1,4-, 1,5-, 1,6-, 1,7-, 1,8-, 2,6- and 2,7-dihydroxynaphthalenes and diphenols represented by the formula: ##STR2## wherein the hydroxyl groups are in the 3- or 4- positions and Y is O, S, SO.sub.2, C.dbd.O, CH.sub.2, CH(CH.sub.3), C(CH.sub.3).sub.2 or (CH.sub.2).sub.3. The aromatic polyesters have superior fire safety performance and are used for film, fiber and molding applications. Rapidly crystallizable polyesters may be obtained with superior solvent resistance and stress cracking resistance.
