Abstract: Thermoplastic molding materials substantially consisting of, in each case, at least one (A) polyalkylene terephthalate having a reduced specific viscosity (measured in 1% strength solution in dichloroacetic acid at 25.degree.C) of at least 0.3 dl/g, (B) nucleating agent, (C) crystallization accelerator, and (D) if required, reinforcing agents and other conventional additives, in which (C) is at least one N,N'-disubstituted asymmetric oxalic acid bismide. The use of such components (C) leads to only little migration and sublimation where moldings produced from the molding material are heated, so that a satisfactory surface quality results. The nucleating agents and accelerators used in the molding material make it possible to reduce the mold temperature to at least 100 to 100.degree.C.

Abstract: 1331840 Copolycarbonamide-phosphonamide filaments FARBWERKE HOECHST AG 17 Dec 1971 [19 Dec 1970] 58866/71 Heading B5B [Also in Division C3] A process for preparing co-poly-carbonamidephosphonamides comprises (a) reacting a phosphonic acid dihalide with at least one molten aromatic diamine and subsequently, after complete reaction, (b) polycondensing the reaction product with at least one aromatic dicarboxylic acid halide. Step (b) is preferably effected in an amide solvent but emulsion or interfaval techniques may also be used. The ratio of phosphonic, carboxylic acids will normally be between 1 : 99 and 30 : 70. The phosphonic dihalide may be a chloride or bromide of an aliphatic, cycloaliphatic or aromatic phosphonic acid, e.g. methyl, ethyl, n- or iso-propyl, cyclohexyl, phenyl, tolyl or naphthyl phosphonic acid. Specified diamines are m- and p-phenylene diamines, benzidine, 4,4 1 -diamino-stilbene and 4,4 1 -diamino-diphenyl-methane, ether-or-sulphone. Specified carboxylic acids are iso- and tere-phthalic and 4,4 1 -dicarboxy-diphenyl, -diphenyl ether or -diphenyl sulphone. Up to 10 mol. per cent of the aromatic diamine and/or diacid may be replaced by a corresponding aliphatic compound. Solutions of the polymers of inherent viscosity above 1 in dimethyl acetamide and 2% CaCl 2 may be spun into dyeable fire-resistant filaments. In examples a 22% solution of the polymer is spun through a nozzle having 100 holes of 150 Á diameter into a coagulation bath of 50 parts water, 10 parts dimethylacetamide and 40 parts CaCl 2 . After several washings the filament is after-drawn and fixed at 300‹ C. the total draw-ratio being 1 : 2À75.
