    Patent number: 4936651
    Abstract: The invention relates to thermoplastically processible mixtures comprising from 0 to 95% by weight of polyamide and from 50 to 5% by weight of polyamide elastomers, especially for the production of polymeric protective layers for optical waveguides. Optical waveguide cables can be produced at higher rates with these mixtures than when using, for example, polyamide 12 alone as the protective layer. The optical waveguide cables thus obtained are distinguished by comparatively low attenuation values even with high mechanical loads.
