<p>The proportion of residual solvent in a solid chlorinated polymer prepared by chlorination in a chlorine-resistant solvent and subsequent treatment with steam or hot water is reduced by carrying out the said treatment in the presence of a polymer lubricant selected from the group consisting of aliphatic carboxylic acids and alcohols having at least 8 carbon atoms and esters and amides of said carboxylic acids, the said polymer lubricant being compatible with the chlorinated polymer in the proportions employed.</p> |
