ABSTRACT:
In a process for recovery of a chlorinated polymer from solution in a chlorinated hydrocarbon solvent by treatment with steam or hot water the retention of residual solvent in the product is reduced by carrying out the treatment in the presence in the solution of an ethoxylate of a primary aliphatic alcohol having at least 8 carbon atoms.
