Abstract

Brominated Styrenic polymer is recovered from solution in a vaporizable solvent by converting the solution in a devolatilization extruder into a brominated styrenic polymer melt. or flow and a separate vapor phase comprised redominately of vaporizable solvent , recovering the melt or flow from the devolatilization extruder , and allowing or causing the melt or flow to solidify. The solidified brominated anionic styrenic polymer can be subdivided into a powder or pelletized form . pellets so made have improved hardness and/or crush strength properties along with reduced formation of fines. brominated anionic styrenic polymer is preferably used in the process.
