Abstract

PURPOSE: To separate a dissolved high molecular substance from an aqueous solution containing the same by kneading the aqueous solution of the water soluble high molecular substance with a viscoelastic substance such as asphalt to effect sorption of said high molecular substance by said viscoelastic substance.
CONSTITUTION: To an aqueous solution of a water soluble high molecular substance such as polyoxyalkylene type compound, PVA, partial saponified substance of ethylene-vinyl acetate copolymer, polyacrylamide or gelatine, highly viscoelastic substance such as wax, atactic polypropylene, atactic polyethylene or polyvinyl acetate is added in an amount of 0.5W2wt times on the basis of the solution and the resulting mixture is kneaded for 1W30min by using a kneader. By this method, a hardly removable water soluble substance can be removed in an extremely simple and efficient manner.
