Pulse Heating as a Tool to Study the High-Temperature Properties of Unstable Liquids

The method of controlled pulse heating of a wire probe in good contact with a liquid has been developed for estimation of the thermophysical properties in the region of instability of this liquid with respect to the temperature and the heat flux. It ensures rapid penetration into the region of short-lived states and maiIntenance of a given temperature in this region. This paper presents and discusses the character of variations of the values of the thermal activity and the lifetime of a system, before its disiIntegration, for thermally unstable liquids, such as polymeric and microheterogeneous systems, for different heating paths.
