摘要: 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.

摘要: 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.
