Linear cyclodextrin‐containing polyelectrolytes, 1. Synthesis of poly(1‐vinylimidazole)‐supported β‐cyclodextrin. Effect of pH and ionic strength on the solution behaviour

A series of linear weak polyelectrolytes containing β‐cyclodextrin pendant groups was synthesized by chemical modification of poly(1‐vinylimidazole). Studies on their solution behaviour as a functon of pH and the nature and ionic strength of added salts showed original features which are explained in terms of competitive residue‐residue and residue‐solvent interactions and anion binding to cyclodextrin moieties.
