Organoantimony compounds of the formula ph3SbX2,where X=Cl,Br and pen-tachlorophenoxy,have been prepared from the reaction of triphenylantimony with CuCl2,bromine and pentachlorophenol respectively. The compounds were characterized by elemen-tal analysis,melting point determination, infrared spectra and thermal behavior. The ther-mal decomposition mechanism was studied in air by differential scanning calorimetry,Theflame retardancy of the compounds in polyvinyl chloride(PVC)was determined,which indi-cated that these compounds had high flame resisting activities for PVC at low additive levels.
