The present invention provides an apparatus and method of reducing volatiles in a mass processable polymer. The apparatus comprises a multi-chambered devolatilizer having first and second collectors contained therein. In one embodiment, the invention provides a method that includes passing the mass processable polymer stream from a polymerization process to a first devolatilizer. The method continues by passing the polymer stream from the first devolatilizer to the multi-chambered devolatilizer. The apparatus and method allows for the production of a polymer having less than 100 ppm of volatiles.
La présente invention concerne un dispositif et un procédé permettant d'extraire des matières volatiles présentes dans un polymère en masse de transformation. Le dispositif comprend une station multichambre d'extraction de matières volatiles renfermant des premiers et seconds collecteurs. Dans un mode de réalisation, l'invention concerne un procédé consistant à faire passer le flux de polymère en masse de transformation d'une station de polymérisation à une première station d'extraction de matières. On fait ensuite passer le flux de polymère de ladite première station à la station multichambre d'extraction de matières volatiles. Ce dispositif et ce procédé permettent d'obtenir un polymère renfermant moins de 100 ppm de matières volatiles.
