Abstract: The authors prepared a series of macroreticular basic resins by using different kinds of aminating agents,percentage of crosslinker and porogenic agents.The resins were characterized and their capacities of decolorization were determined.In addition,the authors also investigated in detail the relation between the decolorization properties and the pore structure,nature of functional groups of resins.The results show that the nature and content of functional groups as well as pore structure of these resins has an important influence on their capacities of decolorization.

Key words: Cross-linked polystyrene, Amino resin, Stevioside, Decolorization
