FLAMEPROOFED HIGH MELTING POINT POLYESTER BASED ON POLYBUTYLENE TEREPHTHALATE AND METHOD OF IMPROVING DECOMPOSITION BEHAVIOR OF FLAMEPROOFED POLYESTER AT THERMOPLASTIC PROCESSING

摘要

1. High-melting polyester based on polybutyleneterephthalate with a flame-resisting finish by means of polymeric bromine-containing flame protecting means, characterised by contents of water-free, finely divided sodium or potassium carbonate in amounts of 0.05 to 1% by weight of the total mixture.
