摘要：

In this paper, studies on the reaction parameters of sulfation of pullulan with SO3, used as a complex with organic bases are reported. The differences in reactivity of pullulan towards dextran sulfation were attributed both to the differences of structures of two polysaccharides and to the differences of their solubilities in the reaction media. The influence of the reaction conditions on the characteristics of the macromolecular chain was investigated. (C) 2001 Elsevier Science Ltd. All rights reserved.
