    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.
