摘要

NEW COMPLEXES HALIDES Bismuth or antimony having the formula (I) and where R is dicyandiamide, guanamine, 2-GUANIDINBENZOIMIDAZOL, isophoronediamine, MELAMINE, piperazine or a compound containing from 2 to 9 RINGS Triazine fused or together by of at least one group -NH-, Me is Bi or Sb; X is chlorine or bromine; Y is a number from 0.3 to 4. These complexes are suitable as flame retardants for thermoplastic polymers.
