The high temperatures and the associated high pressures for devolatization of polymer solutions could be avoided by heating and flashing the polymer solution in more than one and preferably in two stages. Only part of the solvent is flashed off in the first stage so that the temperature does not drop too low, then the polymer rich solution is heated in another heater before the final flash.
