摘　　要：The two flame retardants of 3a and 3b are synthesized from neopentyl alcohol,phospous oxychloride,1,3-dihydroxybenzene and bisphenol-A by a facile and useful method with the yields of 75.2% and 89.7%.respectively.The structures of the two flame retardants are identified and studied by FT-IR,1H NMR,ESIMS and elementary analysis.Reaction conditions are also optimived.The results of thermal analysis show that they have high thermal stability and excellent char-forming ability.Decomposition temperatures of compound 3a and 3b are 312.36 ℃ and 306.39 ℃,respectively.Residual carbons(w%) of compound 3a and 3b under 500 ℃ are 49%and 32%,respectively.The two flame retardants of 3a and 3b are synthesized from neopentyl alcohol, phospous oxychloride, 1,3- dihydroxybenzene and bisphenol-A by a facile and useful method with the yields of 75.2% and 89.7%. respectively.
