Abstract: Patent discloses a method and an apparatus for the recovery of organic solvents from mixtures of organic solvents and polymers soluble or dispersible in the organic solvents. The method comprises the heating, by microwave radiation utilizing a magnetron type radiation source, of the mixture causing said mixture to reach the heat of flashing and/or evaporation of the solvent, collecting the solvent as it so vaporizes and recovering fresh solvent. The dry cake can be discarded or reused depending upon the extent of polymerization.
