Abstract: Phosphorus-containing polycarbonate was synthesized through melt-polycondensation with bisphenol A，diphenyl carbonate，triphenyl phosphite as raw materials and LiOH/LiAc as cata?lysts. The structure，molecular weight and molecular weight distribution，glass transition temperature and thermal stability of the products were characterized with infrared spectroscopy，gel permeation chromatography，differential scanning calorimetry and thermal gravimetric analysis，respectively. Phosphorus-containing polycarbonates with M n =8 700 g/mol，PDI=4. 27，t g =115. 09 ℃ ，700 ℃ carbon residue of 25. 51% and M n =8 000 g/mol，PDI=9. 36，t g =109. 91 ℃，700 ℃ carbon residue of 24. 11% were obtained by the reaction catalyzed with LiOH and LiAc， respectively.
