The present invention relates to an improved falling strand devolatilizer apparatus having a plurality of stages for devolatilization providing polymers with lower residual monomer and/or volatile contents. The novel apparatus utilizes a final flash tank having two flash compartments that share a common heating and vacuum system wherein a recycle line transfers polymer melt from the first compartment to the second compartment for additional devolatilization.
