Synthesis and Flame Retardancy for Polyvinyl Chloride of Organoantimony Compounds

Abstract

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,The flame 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.
