In this paper,β cyclodextrin(β CD) and deoxycholicacid(Deo A) were supported with chloroethyl crosslinked polystyrene respectively and the polymers were characterized by SEM,FTIR and DTA TG.The results indicated that the consecutive reaction take placed between the —CH 2Cl of chloroethyl crosslinked polystyrene and —OH of β CD and Deo A.The thermal stability of β CD supported and Deo A supported was improved and satisfying support results were ...
