The invention relates to polymer mixtures comprising a first polyalkylene phthalate, for example, polybutylene terephthalate, and a second polyalkylene phthalate and/or a thermoplastic elastomer and phosphorus compounds. It has been found that, with regard to the crystallisation behaviour, the addition of certain nucleating agents (namely talcum or carbon black) show a synergistic effect with certain phosporus compounds.
