1. A method of devolatilizing a liquid composition containing a styrene-based polymer and volatile constituents which comprisesfeeding the liquid composition to the inlet of a vertical multi-tube heat exchanger whereby a stream of the liquid composition flows downwardly through each of the tubes of said heat exchanger to thereby raise the temperature of said liquid composition in each said stream,subdividing each of the heat exchanged liquid streams flowing from the outlet of each of said heat exchange tubes into a plurality of subdivided liquid streams by passing each liquid stream through an apertured distributor mounted directly to the outlet end of each respective heat exchanger tube,and volatilizing the plurality of subdivided liquid streams flowing through the apertured distributors in a first volatilization zone located below the vertical multi-tube heat exchanger and apertured distributors.
