Abstract: Glass-fiber-reinforced molding compositions of reduced flammability consisting of (A) a linear saturated polyester resin, (B) from 10 to 60 per cent by weight of glass fibers and (C) from 3 to 30 per cent by weight of a flame retardant. The compositions contain from 2 to 20 per cent by weight, based on the total weight of the molding composition, of a particulate water-insoluble silicate having a bulk density of more than 100 g/l, which prevents dripping of the composition when in contact with an open flame.

Abstract: A process for the preparation of an amide-containing polyether comprises polycondensing a dihalobenzene compound, preferably bis-(4-chlorophenyl) sulfone or 4,4'-bis-(4''-chlorobenzoyl)-diphenyl ether, with an amide-containing bis-phenol of the formula HO-Ar1-NHCO-Ar2-CONH-Ar1-OH where Ar1 is an aromatic radical of 6 to 12 carbon atoms and Ar2 is an aromatic radical of 6 to 12 carbon atoms or has the formula II where A1 is -SO2-, -CO-, -C(CH3)2- or 0 and n is 0 or 1, preferably 1,4-bis(4-hydroxybenzamido)-benzene, in the presence of an anhydrous alkali metal carbonate, and optionally in the presence of a bisphenol of the formula III where Ar1 and A1 have the above meanings and n and m are 0 or 1. The polyethers may be used to produce moldings, fibers, films, adhesives and coating materials.

Abstract: Poly(alkylene terephthalate) molding materials which contain, as the stabilizer, a diepoxide of molecular weight from 200 to 2,000, and a catalyst which is an alkali metal salt of a chelating agent possessing one or more -N(CH2-COO-)2 groups in the molecule. Preferred catalysts are trisodium nitrilotriacetate and tetrasodium ethylenediaminetetraacetate. The molding materials may be used for the manufacture of moldings, films, monofilaments and fibers.
