摘要：

The present paper describes the succinoylation of pullulan by reaction with succinic anhydride in dimethylsulfoxide as solvent and N,N'-dimethylaminopyridine as catalyst. Nuclear magnetic resonance analysis indicated that the carboxylic group is preferably introduced at the C-6 hydroxyl groups. A series of succinoylated pullulan derivatives are prepared with degrees of substitution ranging from 0 to 100%. Activation of the carboxylic groups with N,N'-carbonyldiimidazol and subsequent coupling with amines is discussed.
