"A PROCES FOR PRODUCING POLYETHYLENE TEREPHTHALATE FROM TEREPHTHALIC ACID AND EHYLENE GLYCOL IN THE PRESENCE OF A MONOCARBOXYLIC ACID"

Abstract A method is described for the manufacture of polyesters of aromatic dicarboxylic acids with aliphatic and/or cycloaliphatic diols, in which an aromatic dicarboxylic acid in the presence of a monocarboxylic acid or a mixture of a monocarboxylic acid present in a saturated solution with water or another suitable solvent is converted with an aliphatic or cycloaliphatic diol to a dicarboxylic acid alkanediolestercarboxylate and/or its oligomers, which are polycondensed in further process steps to the polyester.
