Strong pretransitional anomaly near glass transition

In this report we present the first ever results of strong pretransitional effect observed for the maximum of absorption peak $ε_{max}^{''}(T)$ in supercooled liquid-crystalline systems near the glass transition temperature. This anomaly may be described by critical-like relation with critical exponent α=0.5, which corresponds well with previous results for static electric permittivity $ε_{s}(T)$. Such a behaviour may suggest thermodynamic character of glass transition.
