  • Impact-strength-modified polymer compositions
    Publication number: 20040167264
    Abstract: A thermoplastic polyamide molding composition having improved impact strength is disclosed. The composition contains polyamide, an electrically conductive carbon in particulate form and a graft polymer. In one preferred embodiment the composition further contains mineral particles. The composition is especially suitable for direct online lacquering without the necessity for pre-treatment of the molding with an electrically conductive primer system.

  • Impact-strength-modified polymer compositions
    Publication number: 20040167268
    Abstract: A conductive, impact-strength-modified polyamide molding composition is disclosed. The composition contains A) 40 to 99 parts by weight polyamide, B) 0.5 to 50 parts by weight graft polymer, C) 0.1 to 30 parts by weight mineral in particulate form, D) 0 to 1.5 parts by weight electrically conductive carbon particles, E) 0.1 to 15 parts by weight of at least one member selected from the group consisting of polyester ether amide, polyester/ether block copolymer and polyamide/polyester block copolymer. Embodiments that further contain any of compatibility promoter, vinyl (co)polymer, phenolformaldehyde resin and polymer additive are also disclosed. The composition is particularly suitable for online lacquering.
