    Abstract: Recycled plastic moulding material (I) contains (A) 100 pts. wt. recycled polyamide, (B) 5-100 pts. wt. recycled thermoset contg. crosslinked plastic and reinforcing fibres, (C) 0-40 pts. wt. acid gp.- and/or diene gp.- and/or ester gp.-contg. ethylene copolymer and (D) 0-60 pts. wt. normal additives for plastic mixts. Prodn. of (I) comprises melting opt. pulverised (A), opt. with (C), in an extruder, adding pulverised (B) (opt. together with D), homogenising the mixt. and extruding. Pref., (B) contains 20-80 wt.% thermoset, pref. crosslinked UP resin, 10-40 wt.% fibres, pref. glass fibres and 0-70 wt.% filler, pref. chalk. Pref. (B) is used in the form of plastic-coated fibres or fibre bundles with mean length 0.2-1.0 mm, or finely-ground particles with mean dia. 20-100 microns. USE/ADVANTAGE - Used for the prodn. of tubes, profiles, sheet and injection mouldings (claimed). The mechanical properties of recycled polyamide are improved by addn. of recycled reinforced thermoset (B), so that the mixt. can be moulded to give prods. with adequate mechanical properties, esp. rigidity and strength.

    Abstract: Thermoplastic moulding compositions containing A) 4-94% by weight of a partly aromatic, partly crystalline copolyamide having a diamine content of less than 0.5% by weight, built up from (A1) 20-90% by weight of units derived from terephthalic acid and hexamethylenediamine, (A2) 0-50% by weight of units derived from epsilon -caprolactam, (A3) 0-80% by weight of units derived from adipic acid and hexamethylenediamine, (A4) 0-40% by weight of further polyamide-forming monomers, where the proportion of components (A2) or (A3) or (A4) or mixtures thereof is at least 10% by weight, B) 4-94% by weight of a polyolefin homopolymer or copolymer or a mixture thereof, C) 2-20% by weight of an adhesion promoter (coupling agent), D) 0-20% by weight of an impact-modifying polymer, E) 0-60% by weight of additives and processing assistants. %
