Abstract:Copolycarbonate was prepared by interracial polycondensation of bisphenol A,bisphenol S and triphos- gene in the dichloromethane/aqueous NaOH system.The influences of factors on the polymerization were investigated, such as the reaction temperature,the amount of BTC,NaOH,TMBA,and the volume of organic phase.The copolycar- bonate with intrinsic viscosity of 1.28 was obtained.The structure of the polymer was characterized by FT-IR.The result of DSC shows that the Tg of the PC is 157.9℃.The LOI of the copolycarbonate is 0.32.
Keywords:polycarbonates  triphosgene  bisphenol S  flame retardancy  copolmerization
