The reaction of C-phenylcalix[4]resorcinarene-based polymer with quaternary ammonium and potassium cations

摘要

The resol polycondensation of C-phenylcalix[4]resorcinarene with formaldehyde affords a cross-linked plymer possessing ion-exchange ability. The ion-exchange capacity of the polymer with respect to NH_4~+, Me_4N~+, Et_4N~+,Bu_4N~+, and K~+ cations was determined. The equilibrium in the systems C-phenylcalix[4]resorcinarene-based polymer-binary or ternary aqueous solutions of electrolytes was studied by potentiometric titration and quantum-chemical MNDO/PM3 calculation.
