Abstract

PURPOSE: To deposit polystyrene in the form of beads and recover a solvent with a high efficiency, by mixing a specific organic solvent containing the polystyrene with water, distilling off the solvent under heating in the presence of a particulate or granular material, e.g. calcium carbonate or zeolite.
CONSTITUTION: A water-insoluble organic solvent, e.g. benzene, is mixed with water containing 1W30wt% polystyrene dissolved therein, insoluble in water, and having a boiling point lower than that of the water or an azeotropic point with water lower than the boiling point of water is mixed with water in an amount of 0.1 or more, preferably 1W5 times that of the organic solvent, and the resultant mixture is heated with stirring in the presence of one or more particulate or granular materials, consisting of calcium carbonate, zeolite, kaolin, silica sand, diatomaceous earth, bentonite, active carbon and sawdust, and having a particle diameter of 10W300μ in an amount of 0.6 or more, preferably 1W3 time, that of the polystyrene to distill off the solvent.
