A copolyester consisting essentially of ethylene terephthalate units and further comprising 0.01 to 1 mole % based on the sum of the moles of total diol units and the moles of triol units of a triol unit represented by the following formula (I) and/or a triol unit represented by the following formula (II). ##STR1## wherein A is a group represented by formula --CH.sub.2 CH.sub.2 -- or formula --CH(CH.sub.3)CH.sub.2 --, B is a divalent hydrocarbon group, --CO--, --SO.sub.2 --, --0-- or a direct bond (-), and p, q, r, s, t and u are each an integer of 1 to 8. A process for producing the same and molded articles (in particular extrusion blow molded articles) therefrom. The copolyesters of the present invention are applicable to melt moldings accompanying melt extrusion, in particular extrusion blow molding, where parisons therefrom have good draw-down tendency and blow moldability. The copolyesters can give, without causing troubles on molding, molded articles, in particular extrusion blow molded articles, having excellent transparency, heat resistance, moisture resistance and like properties. Aromatic triols usable for producing the above copolyesters are also provided.
