以琥珀酸、富马酸、丁二醇为原料,用共缩聚的方法合成了一系列高分子量聚 (琥珀酸丁二醇酯-共-富马酸丁二醇酯)。然后在催化剂四氧化锇和N-甲基吗啉- N-氧化物以及水存在下,使高分子主链中富马酸丁二醇酯共聚单元的碳碳不饱和双 键发生羟基化反应得到含有亲水性侧羟基的功能性聚酯。对上述合成的生物降解性 高分子运用核磁共振(NMR)、红外(FT-IR)、热分析等方法进行了结构与物理性 能表征。

From starting materials of succinic acid, fumaric acid and 1,4- butanediol, a series of poly (butylene succinate-co-butylene fumarate)s [P(BS-co-BF)] bearing various BF comonomer molar contents were synthesized. Subsequently, the carbon double bonds involved in the copolyester main chain were subjected to dihydroxylation with catalyst of osmium tetroxide (OSO4) , 7V-methyhnorpholine ./V-oxide (NMO) and water to prepare novel biodegradable copolyesters bearing hydrophilic hydroxyl pendant groups. Moreover, these synthesized copolyesters were further characterized by NMR, FT-IR, DSC.

Key words: succinic acid;fumaric acid;BUTANEDIOL;OSMIUM OXIDE;MORPHOLINE P, HYDROXYLATION;NMR;FT;IR;STRUCTURE CHARACTERISTICS;POLYMER
