Abstract

The reaction kinetics in polyelectrolyte solutions were investigated. Acceleration of reactions of two doubly charged counterions by a polyelectrolyte was demonstrated on several systems. Sodium salts of poly(styrene sulfonic acid) and polyacrylic acid (PAA) were found to have their NMR spectral intensities reduced by 27% and 32% respectively. The experiment showed that the collapse of the polymer chain occurred in two stages during the addition of a nonsolvent to an aqueous solution of a polyelectrolyte.
