ABSTRACT:
The invention relates to polymer mixtures comprising a first polyalkylene phthalate and a second polyalkylene phthalate and/or a thermoplastic elastomer. Certain compounds, namely phosphates, have been found to be good transesterification inhibitors. An important advantage of the said inhibitors is that they do not condense, or hardly condense, to polyphosphates and that they do not negatively influence the impact strength of the polymer mixture.
