ABSTRACT:
The latex is treated by passage through a heat exchanger consisting of a closed chamber 1 divided into two distinct superposed parts, the unobstructed upper part 3 being placed under reduced pressure and communicating with a plant for recovery of the residual monomer or monomers, and the lower part 4 being equipped with a partitioning 9 bounding two separate extended and adjoining circuits 10 and 11, one of the circuits 10 being traversed by the latex to be treated and being maintained in communication, via its top and over its entire path, with the upper part 3 of the chamber, and the other circuit 11, isolated from the upper part 3 of the chamber, being traversed by a heat-transfer fluid maintained at a temperature of 40 to 100.degree. C.
Preferably, the two circuits 10 and 11 are bounded by a partitioning 9 arranged in the form of a double spiral.
