Abstract
A horizontal polymer melt distributor is formed from a prism shaped distributor which cooperates with a horizontal tray positioned below the prism shaped distributor. Polymer melt flows into and expands in the distributor then overflows onto the tray. This design holds the polymer melt in the devolatilizer to reduce the content of monomer, dimers and solvent/diluent in the polymer.
