Abstract

L'invention concerne un procédé permettant de faire évaporer des constituants volatils contenus dans des matières polymères fondues, dans un dispositif d'évaporation. Ledit dispositif d'évaporation qui est disposé horizontalement, présente un boîtier cylindrique (10), dans lequel sont placés des disques perforés (5) tournant sur un arbre médian (4), afin de renouveler en continu la surface de la matière fondue à faire évaporer.
