    Abstract: The shaped article consists ofa) from 5 to 95% by weight of a molding composition A made from at least one thermoplastic polyamide, copolyamide or blends of these as component A1, fillers and/or reinforcing materials, if desired, as component A2, impact modifiers as component A3 and other additives and processing aids as component A4, andb) from 5 to 95% by weight of a molding composition B, made from at least one thermoplastic polyamide, copolyamide or blends of these as component B1, at least one crosslinked elastomeric polymer as component B2 and, if desired, other additives and processing aids as component B3,where, in the shaped article, segments of molding compositions A and B are connected to one another over a relatively large area. These shaped articles may be used in the motor vehicle sector, for example as air or coolant ducts.

    Abstract: A hard segment H1 is disclosed with a glass transition temperature of at least 10 DEG C which contains at least one polymerised vinyl aromatic monomer as monomer or one among two or several monomers that can be copolymerised together, at least one cross-linking agent with two or more functional groups of different reactivities and at least one cross-linking agent with two or more functional groups of the same reactivity. The concentration of at least one cross-linking agent varies in the hard segment. A process for producing these segments is also disclosed, as well as graft copolymers which contain these segments, a process for producing these graft copolymers and thermoplastic compounds containing these graft copolymers, moulded bodies, foils, fibres and coatings which contain at least one of the disclosed segments, graft copolymers and thermoplastic compounds.

    Abstract: A thermoplastic molding composition having little intrinsic color is produced from a graft copolymer and a thermoplastic polymer. The graft copolymer is produced from a soft elastomeric particulate graft base obtained by polymerization of a conjugated diene alone or with a small amount of a monoethylenically unsaturated monomer, upon which is grafted a vinylaromatic monomer and acrylonitrile and optionally another monoethylenically unsaturated monomer. The thermoplastic polymer is a copolymer of a vinylaromatic monomer and acrylonitrile and optionally an additional monoethylenically unsaturated monomer. The thermoplastic molding composition has a low level of intrinsic color coupled with good mechanical properties and can be processed by, for example, extrusion, injection molding, calendaring, blow molding, compression molding, or sintering.
