ABSTRACT:
The residual level of monomer in a polymer may be reduced by passing a melt of the polymer through a devolatilizer column which contains an array of two or more trays having voids comprising from 15 to 50% of the surface of the tray which are offset so the voids in the upper tray are spaced over the solid areas of the tray below.
