Abstract: Molding compositions based on polybutylene terephthalate which are flame-retardant and self-extinguishing are obtained by incorporating a mixture of 5 to 30% by weight of a Diels-Alder adduct of hexachlorocyclopentadiene, 1 to 15% by weight of a metal compound having a synergistic action therewith and 1 to 10% by weight of a natural silicate into the polycondensate, the percentages by weight being relative to the amount of polyester used.

Abstract: Process for the continuous manufacture of polymeric starting materials for high-grade transparent thin sheeting, wherein (a) {-caprolactam is continuously agitated in a first reaction zone under polyamide-forming conditions at temperatures of from 240.degree. to 290.degree.C until at least 20% and preferably at least 35% of the {-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 0.0001 to 0.01%, and (c) the melt is then polymerized in further stages to completion until the relative viscosity is from 2.4 to 3.3 and preferably from 2.5 to 2.8.

Abstract: A flameproofed nylon molding composition which can be processed by thermoplastic methods and which contains, as the flameproofing agent, from 5 to 30% by weight of brominated styrene oligomers and a synergistic metal oxide. The compositions may be used for the manufacture of injection moldings for the electrical industry.
