Abstract: Thermoplastic polyester molding compositions showing good impact resistance at both high and relatively low temperatures and containingA. 100 parts by weight of a linear saturated polyester of an aromatic dicarboxylic acid and optionally small portions of aliphatic dicarboxylic acids with saturated aliphatic or cycloaliphatic diols andB. from 1 to 25 parts by weight of a rubber-elastic graft copolymer having a glass temperature below -20.degree. C andC. optionally from 10 to 80 parts by weight of fillers.

Abstract: Reinforced plastics containing an addition of from 0.05 to 2% w/w of a styrene oligomer.

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: Thermoplastic molding compositions of polyoxymethylenes and glass fibers and containing from 0.1 to 5.0 per cent, by weight of the total weight of the mixture, of alkoxymethyl ureas having the formula ##EQU1## where R.sup.1 and R.sup.2 are the same or different and denote straight-chain or branched-chain alkyl of from 1 to 10 carbon atoms and R.sup.3 and R.sup.4 denote hydrogen or alkyl, or R.sup.3 and R.sup.4 are joined together to form a heterocyclic ring with the adjacent ureido group.

Abstract: Glass fiber reinforced polyamide molding material of high impact strength which contains:A. from 40 to 90 parts by weight of a polyamide; andB. from 10 to 60 parts by weight of glass fibers coated with a film-forming polymer containing from 4 to 50% by weight of units of the general formula: ##EQU1## in which R.sup.1 is hydrogen or alkyl of one to five carbon atoms and R.sup.2 is a saturated divalent hydrocarbon radical of two to ten carbon atoms; with or withoutC. a conventional stabilizer, flame retardant, pigment, filler or other additive.

Abstract: Cyclic phosphorus nitride esters are prepared as flameproofers of high durability for use on regenerated cellulose. The known synthesis from cyclic phosphorus nitride chlorides with alcohols in the presence of amines is controlled under specific temperature conditions such that desired side-reactions permit the production, in a simple manner and in very high yields, of products showing a durability to washing not hitherto achieved.

Abstract: Glass reinforced thermoplastic molding material pigmented with inorganic pigments and characterized by improved mechanical properties. Molding material according to the invention contains a pigment having a Mohs hardness of less than 5.
