Abstract: The invention relates to a process for the preparation of a hollow filament (F) based on one or several molten or dissolved hyperbranched polymers (P) and potentially one or several further polymers (FP), characterized in that the molten or dissolved hyperbranched polymer (P) or the mixture of the hyperbranched polymer (P) with the further polymer (FP) is passed through one or several spinnerets (S), wherein the ratio between the spinneret die-length (L) and the die-channel (Delta-D) is between 0.1 and 9.5. The process can be applied for the preparation of hyperbranched polyethersulfone (HPES) hollow filaments.

Abstract: A thermoplastic moulding composition with improved metal plating properties is provided. This thermoplastic moulding composition is produced from a graft copolymer (A) a thermoplastic polymer (B) and a thermoplastic polymer (C) that is not, or only to a limited amount miscible with the thermoplastic polymer (B). The thermoplastic polymer (C) contains from 1 to 10 % by weight of at least one monoethylenically unsaturated monomer, like acrylic acid, methacrylic acid, or dicarboxylic acids, such as maleic acid and fumaric acid and their anhydrides, such as maleic anhydride. The vinyl aromatic content of component (C) is at least 5 units lower compared to that of component (B). The graft copolymer is produced from a soft elastomeric particulate graft base with a glass transition temperature below 0°C obtained by emulsion polymerization of a conjugated diene alone or with a small amount of a monoethylenically unsaturated monomer or of at least one C1-8-alkyl acrylate, or of mixtures of these, upon which is grafted a vinyl aromatic monomer and acrylonitrile and optionally another monoethylenically unsaturated monomer.
