Bubble Nucleation in Polymeric Liquids Under Shock Processes

This paper studies the phenomenon of spontaneous boiling-up of polymeric liquids on heating at rates (T) up to 107 K . s - l . A model of the thermal equation of state for (polymer + monomer) systems and a procedure for determination of the spontaneous boiling-up temperature T* for polymeric liquids, taking decomposition into account, are proposed. The experimental data on T*( T) for a number of polymer melts are compared with results calculated from the model.
