    Abstract: Thermoplastic moulding material of the following composition (I): (A) 30 to 97 weight % of a thermoplastic polyester or polyamide or of a mixture of said polymers, whereby said polymers or their mixture have a viscosity index greater than 165; (B) 3 to 40 weight % of an olefin polymerizate, comprised of (b1) 40 to 100 weight % of at least one alpha -olefin with 2 to 8 atoms of C, (b2) 0 to 50 weight % of a diene, (b3) 0 to 45 weight % of a primary or secondary C1 to C12 acrylic acid or methacrylic acid alkylester or mixtures of such esters, (b4) 0 to 40 weight % of an ethylenically unsaturated monocarboxylic or bicarboxylic acid and/or a functional derivative of such an acid, (b5) 0 to 40 weight % of a monomer containing epoxy groups, with the provision that the component (B) is not an olefin homopolymerizate and that it has a gel content no greater than 50 %; (C) 0 to 60 weight % of fillers in fibre or particle form, or mixtures thereof; and (D) 0 to 40 % of a flame protection agent; or of the following composition (II): (A) 20 to 99 weight % of a thermoplastic polyester or polyamide or of a mixture of said polymers; (D) 1 to 40 weight % of a flame protection agent; (B) 0 to 20 % of an olefin polymerizate; and (C) 0 to 60 weight % of fillers in fibre or particle form or mixtures thereof. Said thermoplastic moulding materials can be produced by thermal treatment of mixtures of a type (A) component (component A'), whose viscosity index is lesser than 160, with the remaining components, at temperatures between 60 DEG C below and 60 DEG C above the melting point of the pure component (A).

    Abstract: The shaped body consists of a) 5 to 95 wt. % molding material A comprising at least one thermoplastic polyamide, copolyamide or a blend thereof as constituent A1, optionally filling and/or reinforcing substances as constituent A2, impact resistance modifiers as constituents A3 and other auxiliary and processing agents as constituent A4 and b) 5 to 95 wt. % of a molding material B comprising a thermoplastic polyamide, copolyamide or the blends thereof as constituent B1, at least one chained rubber-elastic polymer as constituent B2 and optionally other auxiliary and processing agents as constituent B3. The segment surfaces of molding materials A and B are joined to each in the shaped body. The inventive shaped bodies can be used in the automobile industry, e.g. as air or coolant ducts.

    Abstract: The invention relates to a process for the preparation of reinforced, impact-modified thermoplastic molding compositions which contain, based on 100 parts by weight, A) from 30 to 93 parts by weight of one or more thermoplastics from the group comprising the polyamides, polyesters, polycarbonates and polyphenylene ethers, B) from 5 to 50 parts by weight of fibers, preferably glass fibers, and C) from 2 to 20 parts by weight of one or more impact-modifying rubbers, in which process the fibers (B) are first introduced into the melt of the thermoplastic (A), components (A) and (B) are mixed, the rubber (C) is then introduced into the resultant mixture in the melt, and the resultant molding composition is extruded and granulated, wherein the reaction is carried out in one step, expediently at a constant temperature in the range of, advantageously, from 250 DEG to 300 DEG C.

    Abstract: Flameproofed thermoplastic molding materials contain (A) 40-99% by weight of a partly aromatic amide copolymer consisting essentially of (a1) 40-50% by weight of units derived from terephthalic acid and hexamethylenediamine, (a2) 0-50% by weight of units derived from epsilon -caprolactam and (a3) 0-60% by weight of units derived from adipic acid and hexamethylenediamine, components (a2) and/or (a3) accounting altogether for not less than 10% by weight of the total number of units, (B) 1-30% by weight of a flameproofing combination of (b1) 40-97% by weight of red phosphorus, (b2) 1-50% by weight of an inorganic compound of a divalent or tetravalent metal, (b3) 1-40% by weight of an organic mono- or dicarboxylic acid and (b4) 1-40% by weight of an ester of an organic carboxylic acid of 6 to 24 carbon atoms with an alcohol of 2 to 24 carbon atoms or of a metal salt of such an acid, or a mixture of these, (C) 0-60% by weight of fibrous or particulate fillers or a mixture of these, and (D) 0-40% by weight of a polymeric impact modifier.
