    Abstract: Thermoplastic molding compositions having good heat resistance, weather resistance and dimension stability are produced from polyesters and polycarbonates and/or styrene copolymers. A thermoplastic molding composition comprises (a) 1-99 wt.% polyester (A); (b) 0-98 wt.% polycarbonate (B); (c) 1-80 wt.% graft copolymer (C) consisting of (1) 1-95 wt.% material (C1) with a glass transition temperature of at least 25 deg C and an average particle size of at least 50 nm consisting of (i) 50-99.99 wt.% vinyl aromatic monomer (C11); (ii) 0-49.99 wt.% monomer (C12); (iii) 0.1-25 wt.% crosslinker (C13) selected from 0.1-100 wt.% dihydrocyclopentadienylacrylate and 0-99.99 wt.% of a further crosslinker with two or more functional groups; and (iv) 0-25 wt.% crosslinker (C14) with two or more functional groups; (2) 4.9-98.9 wt.% material (C2) having a glass transition temperature of at least 0 deg C consisting of (I) 50-100 wt.% alkylacrylate (C21); (II) 0-50 wt.% monomer (C22); and (III) 0-20 crosslinker (C13); and (3) 0.1-90 wt.% further grafting component (C3); (d) 0-80 wt.% styrene copolymer (D); (e) 0-30 wt.% rubber (E); (f) 0-60 wt.% fibrous or particulate filler (F); and (g) 0-20 wt.% further additives.

    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.
