摘　　要：5,5-Dibromomethyl-2-chloro-2-oxo-1,3,2-dioxaphosphorinane)(Ⅱ)was prepared by reaction of dibromoneopentyl glycol and phospous oxychloride in the presence of triethylamine.Then bis(5,5-dibromomethyl-1,3,2-dioxanephosphoryl)bisphenol A(Ⅲ)was synthesized by compound Ⅱ and bisphenol A.The overall yield was 78.8%.The structure of the novel flame retardant was confirmed by elementary analysis,IR,MS and 1H NMR spectroscopy.The termogravimetry showed that the novel flame retardant had high thermal stability and excellent char-forming ability.The beginning temperature of the compound Ⅲ decomposition was above 264.2 ℃,and the char yield was about 17.50% at 600 ℃.5,5-Dibromomethyl-2-chloro-2-oxo-1,3,2-dioxaphosphorinane） （ Ⅱ） was prepared by reaction of dibromoneopentyl glycol and phospous oxychloride in the presence of triethylamine.
