  • Patent number: 6770378
    Abstract: Compounds which, for example, can be used as a compact substance and which are comprised of polyamide substance(s) and perfluoralkyl substance(s), and to mixtures of these compounds with additional polymer substance(s). Methods for producing such compounds are also provided in which aliphatic and/or partially aromatic homopolyamides and/or copolyamides and/or polyester amides and/or polyether amides and/or polyester ether amides and/or polyimide amides and/or polyamide amides and/or mixtures of these polyamide compound(s) with additional polymer(s) and modified perfluoralkyl substance(s) are compounded in a single step or multistep and are reactively converted during or afterwards. The homogenization of perfluoralkyl substance(s) in polyamide substance(s) melted masses is improved.
