  • COMPOSITE PART CONSISTING OF A FILM AND A SUBSTRATE BASED ON AN AMORPHOUS POLYAMIDE
    Publication number: 20100055425
    Abstract: A film which comprises a layer composed of a moulding composition composed of a semicrystalline polyamide whose enthalpy of fusion is at least 8 J/g is used for production of a composite part with a substrate composed of a moulding composition composed of a substantially amorphous polyamide whose enthalpy of fusion is less than 8 J/g.

  • COMPOSITE PART MADE OF A MULTI-LAYER FILM AND A SUBSTRATE BASED ON A POLYCARBONATE
    Publication number: 20100003524
    Abstract: A composite part is composed of I. a multilayer film, which comprises the following layers: a) a layer composed of a polyamide moulding composition and b) following in the inwards direction, a layer composed of an adhesion promoter, which comprises from 5 to 100% by weight of a copolymer, which contains the following monomer units: from 70 to 99.9% by weight of monomer units which derive from vinyl compounds selected from acrylic acid derivatives, methacrylic acid derivatives, ?-olefins and vinylaromatics, and from 0.1 to 30% by weight of monomer units which contain a functional group selected from a carboxylic anhydride group, an epoxide group and an oxazoline group, and II. a substrate composed of a polycarbonate moulding composition.

  • MULTIPLE LAYER FILM AND COMPOSITE MATERIAL PRODUCED THEREFROM
    Publication number: 20090286096
    Abstract: A film comprising the following layers: I. a layer based on a polyamide whose monomer units contain an average of at least 8 carbon atoms, II. an immediately adjacent layer composed of a moulding composition comprising a polyamide as in I. and a copolymer having functional groups is used for the production of a composite with a substrate which comprises PA6, PA66, PA6/66 or PPA, giving secure adhesion.
