ABSTRACT:
Self-extinguishing molding compositions based on polybutylene terephthalate which do not drip flaming particles on exposure to a flame and which contain a compound containing halogen, which is stable under the conditions required for processing the melt, and a synergistically active metal compound, are obtained by incorporation of a magnesium silicate of the chrysotile type into the polycondensate.
