Abstract

The mixtures according to the present invention of polyalkylene terephthalates, certain new polycarbonates and/or polyester-carbonates and elastomers have a particularly favourable low temperature strength/heat distortion point relationship compared with conventional moulding compositions containing known polycarbonates. The mixtures are used for the production of, in particular, shaped articles.
