Abstract: Impact-resistant polyoxymethylene molding materials containing (A) from 30 to 95% by weight of one or more polyoxymethylenes and (B) from 5 to 70% by weight of one or more elastomeric graft polymers which are prepared by emulsion polymerization, are dispersed in component A, have a mean particle diameter of from 0.08 to 2 mu m and are composed of 1. from 60 to 90% by weight of a grafting base of crosslinked polybutadiene in which not more than 30% by weight of the butadiene may be replaced with isoprene, 2,3-dimethylbutadiene, styrene, p-methylstyrene, alpha -methylstyrene and/or (meth)acrylonitrile, and 2. from 10 to 40% by weight of one or more grafted shells consisting of polymers of styrene and/or methyl methacrylate, in which not more than 15% by weight of the said monomers 2 may be replaced with acrylonitrile or a C1-C8-alkyl acrylate, the percentages A and B and the percentages 1 and 2 summing to 100, with or without (C) effective amounts of assistants, and a process for their preparation.

Abstract: The invention relates to moulding compositions comprising (A) at least one polyoxymethylene homopolymer and/or copolymer, (B) at least one thermoplastic polyurethane elastomer and (C) optionally additives, which contain, in order to improve the heat resistance, reduce the tendency toward discoloration and minimise the free formaldehyde content, (D) at least one alkaline earth metal carbonate, alkaline earth metal hydroxide carbonate, alkaline earth metal glycerophosphate or a mixture of at least two of the said compounds, expediently in an amount of from 0.005 to 2% by weight, based on the weight of the components (A) and (B), as additive. In order to prepare the moulding compositions, components (A), (B), (D) and, if used, (C) are advantageously melted together in an extruder at temperatures of from 150 to 260 DEG C. The moulding compositions are suitable for the production of films or mouldings used, for example, in the automotive, electrical appliance and electronics industries.

Abstract: Polyoxymethylene moulding compositions having improved sliding properties contain, as lubricant, from 0.3 to 5% of a hydroxycarboxylic acid ester made from a) a hydroxycarboxylic acid having 3 to 30 carbon atoms and b) one or more alkanols having 10 to 25 carbon atoms. The moulding compositions are suitable for the production of mouldings, such as bearing elements.

Abstract: 1411841 Oxymethylene polymer-glass fibre compositions BADISCHE ANILIN- & SODAFABRIK AG 28 Feb 1973 [2 March 1972] 9722/73 Heading C3P Oxymethylene homo- and copolymers are compounded with glass fibres and a thermoplastic polyurethane. The composition may typically be obtained by melting the polymers in a twin-shaft extruder, adding the glass fibres, extruding the melt and injection moulding the resulting granules. In the examples trioxan-ethylene oxide or -dioxolan copolymers are mixed with glass fibres, sometimes having had a vinyl triethoxysilane or glycideoxypropyl trimethoxy silane treatment, and with polyurethanes derived from polyethylene glycol adipate, 4,4 1 -diphenylmethane diisocyanate and 1,4-butane diol or from an adipic acid/hexane diol/neopentylglycol copolyester, hexamethylene diisocyanate, and butane-diol-1,4.
