  We present a non-isothermal mesoscopic model for investigation of the phase
transition dynamics of thermoresponsive polymers. Since this model conserves
energy in the simulations, it is able to correctly capture not only the
transient behavior of polymer precipitation from solvent, but also the energy
variation associated with the phase transition process. Simulations provide
dynamic details of the thermally induced phase transition and confirm two
different mechanisms dominating the phase transition dynamics. A shift of
endothermic peak with concentration is observed and the underlying mechanism is
explored.
