Abstract: Thermoplastic molding compositions based on polybutylene terephthalate having a relative viscosity of from 1.3 to 2.0, as measured in a phenol/o-dichlorobenzene mixture at 25 DEG C, and which contain, to increase the thermo-aging stability and toughness and also to improve the processing stability, from 0.1 to 10% by weight, based on the polybutylene terephthalate, of isocyanates or isothiocyanates and/or carbodiimides and/or compounds forming isocyanate groups or isothiocyanate groups and/or carbodiimide groups.

Abstract: Stabilisation is achieved against heat and oxidn. by adding aziridines (I) (where R is a 1-18C aliphatic gp. opt. substd. by Oh, CN, carbamido or carboxyalkyl. R can also be alkylene, aryl, cycloalkyl or acyl. No.n= 1-3). Stabiliser quantity may be 0.01-5 (0.1-1) wt. % wrt. polymer. Polybutylene terephthalate used has relative viscosity 1.3-2 (1.5-1.7), measured in 0.5% soln. at 25 degrees C in phenol/o-dichlorobenzene mixt. having wt. ratio 3:2. Injection-moulded articles and films resist heat-ageing.

Abstract: Process for the continuous manufacture of polymeric starting materials for high-grade transparent thin sheeting, wherein A. epsilon -CAPROLACTAM IS CONTINUOUSLY AGITATED IN A FIRST REACTION ZONE UNDER POLYAMIDE-FORMING CONDITIONS AT TEMPERATURES OF FROM 240 DEG TO 290 DEG C until at least 20% and preferably at least 35% of the epsilon -caprolactam has reacted, B. MAGNESIUM SILICATE HAVING A PARTICLE SIZE OF LESS THAN 30 mu M IS THEN ADDED TO THE MELT TO GIVE MAGNESIUM SILICATE CONCENTRATIONS IN THE REACTION MIXTURE OF FROM 0.0005 TO 0.5% AND PREFERABLY FROM 0.001 TO 0.

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.
