Abstract
The process of the parent Specification, in which chlorinated rubber is separated from its solution by spraying in the presence of a condensible vapour, e.g. steam, at a temperature at or above the boiling point of the solvent is carried out in the presence of an alkali, for stabilizing purposes. The alkali as vapour or finely divided solid, may be blown in by the atomizing medium for the chlorinated solution, or it may be added to liquid into which the solution is sprayed. One per cent of NaOH is a suitable concentration.
