A mixture of polymers comprising: a. 2 to 20 percent by weight of one or more epoxy-containing polymers that modify the impact, based on the total weight of the polymer blend and b. one or more homopolymers or copolymers of ethylene polyterephthalate comprising aluminum atoms in an amount of 3 ppm to 60 ppm and one or more alkaline earth metal atoms, alkali metal atoms or alkaline compound residues in an amount of 1 ppm to 20 ppm, preferably 5 ppm to 18 ppm, additionally preferably 8 ppm to 15 ppm, in each case based on the weight of the one or more homopolymers or copolymers of ethylene polyterephthalate. |
