ABSTRACT:
A process for the preparation of chlorinated aliphatic polymers wherein chlorine-free polymers are chlorinated by using gaseous chlorine in chlorinated hydrocarbons as solvents and the chlorinated aliphatic polymers are recovered from the chlorinating solution by steam distillation in which process from 15 to 50% by weight of a lacquer resin is added to the chlorinating solution before steam distillation. The chlorinated polymers contain less residual solvent.
