    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.

    IPC: C08L77/00

    Abstract: The moulding compositions contain, as essential components, A) 10-89% by weight of a copolyamide made from A1) 80-99% by weight of recurring units derived from adipic acid and hexamethylenediamine, and A2) 1-20% by weight of units derived from epsilon -caprolactam, B) 10-89% by weight of polyhexamethyleneadipamide, C) 1-40% by weight of an impact-modified rubber, and, in addition, D) 0-60% by weight of fibrous or particulate fillers or mixtures thereof.

    Abstract: Fully aromatic thermotropic polyesters based on (A) from 30 to 60 mol % of 4-hydroxybenzoic acid, (B) from 20 to 35 mol % of a mixture of (B1) terephthalic acid, (B2) isophthalic acid and (B3) from 0.5 to 5 mol % of a dicarboxylic acid of the general formula I where X is -O-, -S-, -SO2-, -CO-, -CH2- or -C(CH3)2-, n is 0 or 1 and the two imide nitrogen atoms are meta or para to X, or their C1-C8-alkyl, C1-C8-alkoxy, aryl, chlorine or bromine derivatives which are substituted in the nucleus, the molar ratio of B1 to B2 being from 1.04:1 to 19:1, and (C) from 20 to 35 mol % of a mixture of (C1) hydroquinone and (C2) 4,4'-dihydroxydiphenyl, the molar ratio of C1 to C2 being from 0.1:1 to 2.67:1 and the molar ratio of B to C being from 0.9:1 to 1.1:1.
