摘　　要：脂肪族聚碳酸酯作为生物材料已引起普遍关注[1], 由于其良好的生物相容性、表面溶蚀性和无毒性, 在医学领域中得到越来越广泛的应用.New polycarbonates were synthesized by ring-opening polymerization from the protected cyclic carbonate 9-phenyl-2,4,8,10-tetraoxaspiro-[5,5]undecan-3-one in bulk at 190 'C under the catalysis of various catalysts, such as aluminum isobutoxide [Al(O'Bu)3], aluminum isopropoxide [Al(O'Pr)3] or stannous octanoate [Sn(Oct)2]. The effects of different catalysts, reaction time, and monomer-to-catalyst molar ratio on the molecular weight and yield were investigated. The polycarbonates obtained were characterized by FTIR,1H NMR, GPC and DSC. The protecting benzal group was removed by hydrolysis with 80% acetic acid to give a functional polycarbonate containing 45% hydroxyl group.
