Abstract

A process of separating a polymer-monomer mixture into a solid fraction comprising the polymeric components and a gaseous fraction comprising the gaseous components containing monomers; the process comprising the step of: introducing the polymer-monomer mixture into a separation vessel comprising at least a filter bag, a first outlet for the gaseous fraction and second outlet for the solid fraction, which is on an opposite side of the filter bag with respect to the first outlet; applying a depression inside the filter bag so that the gaseous fraction passes through the filter bag and goes out of the vessel through the first outlet; and discharging the solid fraction through the second outlet; the filter bag comprises a filtering layer 9, which is comprises aramid fibers superficially coated with at least one perfluorocarbon.
