摘要： 脂肪族聚碳酸酯作为生物材料已引起普遍关注,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.迄今已报道的许多脂肪族聚碳酸酯的降解速率相对较慢,如聚三亚甲基碳酸酯的降解速率比聚乳酸和聚己内酯慢很多.但是,如果在聚碳酸酯的侧链上引入亲水性功能基团,其降解速率将会明显提高.

Abstract: 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 'Cunder 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, 1HNMR, GPC and DSC. The protecting benzal group was removed by hydrolysis with 80% acetic acid to give a functional polycarbonate containing 45% hydroxyl group.

Key words: Functional polycarbonate, Ring-opening polymerization, Hydrolysis, Hydrophilicity
