摘　　要：A new polymer-bonded β-cyclodextrin was prepared fromchloromethylated styrene-divinylben- zene copolymer, sodium salt of β-cyclodextrin (β-CD), KI, and (C_4H_9) 4N^+I^- in a molar ratio ofCl: β-CD: I = 1 : 1.5 : 1. Element analyses showed that β-CDcontent in the above catalyst was 701 umolg^-1.A new polymer-bonded β-cyclodextrin was prepared fromchloromethylated styrene-divinylben- zene copolymer, sodium salt of β-cyclodextrin (β-CD), KI, and (C_4H_9) 4N^+I^- in a molar ratio ofCl: β-CD: I = 1 : 1.5 : 1.
