    Abstract: The flowability of polyamides is improved by kneading them with an acetylenic alcohol having a boiling point above 100 DEG C. at atmospheric pressure, e.g. with 0.05 to 2.5 wt. per cent thereof at 180 DEG to 350 DEG C. Specified polyamides are various polylactams or polycondensates of aliphatic dicarboxylic acids and polymethylene diamines or 2,4-di-(aminomethyl)-toluene of K-value 65 to 1000. They may also contain dyes, fillers, stabilizers, lubricants, mould-release agents or crystallization accelerators. Various alcohols are specified. In Examples (1) and (2), Nylon 6 is kneaded with (1) 0.3% 1-ethynyl-cyclohexanol-1, 0.3% calcium stearate and 0.1% Nylon 2,2 or (2) 0.5% 2,6-dimethyl-2-methoxy-6-hydroxy-octin (7), 0.5% calcium stearate, 0.1% nylon 2,2 and 0.2% t-butyl-p-cresol; (3) Nylon 6,6 is kneaded with 0.5% 1-ethynylcyclohexanol-1, 0.1% Nylon 2,2 and 0.3% cadmium sulphide; and (4) Nylon 6,10 is kneaded with 20.4% 2,6,10,14-tetramethyl-hexadecyn-(15)-ol-(14), 0.5% calcium stearate, 0.1% Nylon 2,2 and 0.08% halogenated copper phthalocyanine.

    Abstract: A moulding composition comprises a mouldable organic synthetic plastics, 0.01-5% by wt. of an inorganic acicular or lamelliform pigment having a smooth surface and 5-60% of fibres of length 2-2000 m which are not soluble in the plastics and do not melt under the conditions met in the production of an article which may be produced from this composition. The plastics may be polystyrene, an unsaturated polyester/styrene resin, or polycaprolactam. The pigment may be aluminium or a copper/zinc alloy. The fibres may be of glass which may be fed as a bundle into a melt of the plastics and then comminuted to the given length. The polycaprolactam based composition may contain calcium stearate as lubricant.
