Abstract

A process for the preparation of a chlorinated aliphatic polymer which comprises chlorinating a chlorine-free aliphatic polymer in a chlorinated hydrocarbon solvent using gaseous chlorine as the chlorinating agent; adding from 2 to 25% by weight, based on the chlorinated polymer, of at least one plasticizer and/or at least one lacquer resin, to the chlorination solution; and isolating the chlorinated aliphatic polymer from the chlorination solution by steam distillation.
