Abstract
Poly(methacrylic acid) (PMA) at low degrees of ionization adopts a conformation which resists expansion of the coil with the increasing charge density associated with increasing pH. This study explores the pH dependent reversible complexation with the cyclodextrin to other binaphthyl labeled polyelectrolytes, poly(acrylic acid) (PAA), poly(ethacrylic acid) (PEA) and the acidified alternating copolymer of maleic anhydride and butyl vinyl ether (BVE-Mac). Of these polyelectrolytes, PEA and BVE-Mac have the characteristic titration curves found for MPA which signal the pH dependent potential to form hydrophobic clusters while the titration curve for PAA shows no resistance to expansion of the coil at low pH which characterizes this property.
