    Abstract: A reinforced moulding compsn. contains (A) a polyoxymethylene (co)polymer, (B) wollastonite with average thickness not above 5 microns and average length:thickness ratio at least 5, and opt. (C) additives. Pref. the compsn. contains 95-50 pts. wt. of polyoxymethylene, 5-50 pts. of wollastonite, and 0-60 pts. of additives. The polymer has Mw 2,000-100,000, and MFI of 0.5-200 at 190 deg.C and 21.17N. The wollastonite crystals are added by means of an extruder to the polymer melt, esp. at 180-260 deg.C.

    Abstract: Fiber-reinforced materials are produced by a process in which a heat-stable thermoplastic aromatic polyether A which contains reactive groups, preferably nitrile groups and/or sulfur bridges and/or arylthio or alkylthio groups, if necessary together with a heat-stable thermoplastic polymer B which does not contain any reactive groups, is applied onto reinforcing fibers, the resulting semi-finished product is molded and, in the molding obtained, the plastic matrix is crosslinked so that the glass transition temperature increases and it becomes virtually insoluble.
