    • A process for preparing a high molecular weight heteraromatic polyester or copolyester is disclosed. A process for preparing a high molecular weight heteroaromatic polyester or copolyester includes the steps of: (a) processing comonomers by mixing together to form a homogeneous solution (1) at least one heteroaromatic dicarboxylic acid having 2-12 carbon atoms or a diester or an acid anhydride derived therefrom, or a mixture thereof; (2) at least one alcohol having 2 to 12 carbon atoms and at least two hydroxyl functionalities; and (3) optionally aromatic or aliphatic dicarboxylic acids or diesters or acid anhydrides derived therefrom; (b) converting the paste/solution obtained in step a) into an esterification product containing at least one diester or at least one oligoester formed from the at least one heteroaromatic dicarboxylic acid and the at least one alcohol; and (c) polycondensing/copolycondensing the reaction product obtained from step b) under reduced pressure.
