REMOVING SOLVENT FROM ELASTOMERS

A process for the removal of a C6-7-hydrocarbon solvent from an elastomer composition in a devolatilization zone under such conditions of pressure and temperature that the solvent evaporates from the composition, which comprises mixing an amount of a pentane with the composition after polymerization...
