ABSTRACT:
Carbonate-modified copolyesters which are suitable for the production of mouldings by injection moulding or for the production of pipes, films and fibers by extrusion, can be obtained by reacting aromatic dicarboxylic acids or their ester-forming derivatives and carbonic acid esters of dihydric aliphatic alcohols which have carbonic acid ester groupings in the molecule and hydroxyalkyl end groups.
