Claims
- 1. A polymer mixture consisting essentially of:
- A) a first polyalkylene phthalate, and
- B) a component selected from the group consisting of: B1) a second polyalkylene phthalate which is not equal to the first polyalkylene phthalate; B2) a thermoplastic elastomer selected from a polyether ester block copolymer, a polyester ester urethane and a polyether imide ester; and B3) a mixture of B1 and B2, wherein the weight ratio of constituent A to constituent B lies between 5:95 and 95:5, and
- C) mono zinc dihydrogen phosphate as a transesterification inhibitor being present in an amount from 0.01 to 2 parts by weight per 100 parts by weight A and B, and
- D) a core-shell graft polymer for improving impact resistance.
- 2. A polymer mixture as claimed in claim 1, wherein the polymer mixture comprises a first and/or a second polyalkylene phthalate having more than 70 mol.% of units derived from terephthalic acid and ethanediol or butane-1,4-diol.
- 3. A polymer mixture as claimed in claim 1, wherein the first polyalkylene phthalate is polybutylene terephthalate and the second polyalkylene phthalate is polyethylene terephthalate.
- 4. A polymer mixture as claimed in claim 1, wherein the first polyalkylene phthalate is polybutylene terephthalate and constituent B2 is a polyether ester block copolymer.
- 5. A polymer mixture as claimed in claim 1, wherein the polymer mixture moreover comprises one or more of the following additives: flame-retardant additives, reinforcing and non-reinforcing fillers, oxidation stabilisers, mould release agents, processing additives, dyes and pigments.
- 6. Articles formed from the polymer mixture as claimed in claim 1.
