Comment on ‘‘The effect of charged impurities on a glass transition in a polar medium’’ [J. Chem. Phys. 104, 664 (1996)]

Dakhnovskii and Lubchenko have recently presented a theory to predict the effect of charged impurities on the glass transition temperature (Tg) in a polar medium. We present and cite more extensive sets of experimental results that show that the electrolyte concentration required to induce a 10 K increase in Tg is nearly three orders of magnitude greater than that predicted from their theory.
