Stabilization of ion radicals by polyelectrolytes and dimerization kinetics of dialkyl viologens, Synthetic Route of 36437-30-6, the main research area is viologen cation radical dimerization polyelectrolyte stabilizer.
The dimerization kinetics of reduced dialkyl viologens (di-C4, di-C7, and di-C8 cation radicals) was studied in the presence of polyelectrolytes poly(styrenesulfonate) (PSSH) or the polysoap MA-CVE (maleic acid/cetyl vinyl ether copolymer). Three kinetic models were considered: total dimerization (I), reversible dimerization (II) with initial concentration of reduced viologen equal to the stoichiometric concentration, and (III) reversible dimerization with finite dimer at time 0. In the absence of polyelectrolyte, the quality of fit to the exptl. kinetics was independent of model I-III; the rate of dimerization increased from di-C7 to di-C8, consistent with decreasing solubility and increasing degree of association in this series. The disappearance of reduced viologen is suppressed by polyelectrolyte; here, too, models I-III did not drastically differ.
