A novel phosphorus-containing copolycarbonate was synthesized from bisphenol-A,2-(6-oxido-6H-dibenz
<1,2>oxa phosphorin-6-yl)-1,4-dihydroxy phenylene(ODOP-HQ) and triphosgene by interfacial polycondensation,and a copolycarbonate with an inherent viscosity of 0.53 dL/g was obtained.The copolymer was characterized by elemental analysis,FT-IR,DSC,TGA,and NMR.DSC result shows that the Tg of the copolycarbonate is 149℃,which is higher than that of normal PC.The TGA result shows that the onset decomposition temperature of the copolycarbonate is 355℃,which indicates it possesses a good thermal stability. -
