Abstract

The present invention relates to a process for the removal of solvent from a polymer emulsion or suspension, by use of a decanter centrifuge (10). The decanter centrifuge (10) provides an efficient thickening method. The process is especially useful for emulsion or suspension polymer compositions having high levels of solvent (low polymer solids) that could benefit from a thickening or dewatering step prior to drying in a dryer (14).
