摘要： The invention relates to a method for producing polyesters of aromatic dicarboxylic acids with aliphatic and/or cycloaliphatic diols, during which an aromatic dicarboxylic acid present in a saturated solution is, in the presence of a monocarboxylic acid or of a mixture of a monocarboxylic acid with water or in another suitable solvent, reacted with an aliphatic or cycloaliphatic diol to form a dicarboxylic acid alkane diolester carboxylate and/or oligomers thereof, which can be polycondensed in additional method steps to form polyester.

摘要： The invention relates to mixtures that comprise at least one polyester precursor and at least one alkali metal salt and/or alkaline earth metal salt, said mixture comprising at least one phosphonic ester of formula (I) (RO)OC-R'-PO(OR)2, wherein R independently represents a group having 1 to 60 carbon atoms and R' represents a linking group having 1 to 20 carbon atoms. The invention also relates to polyester compositions obtained from the aforementioned mixtures and to polyester films.
