Polymer Solvent Drying

Problem: The production of many petroleum and biomass based polymers involves contact with chemical solvents. This contact may occur during the polymerization/reaction step, or to extract impurities from the final product. Typically, the liquid solvent is first removed mechanically by centrifuge or filter. However, after mechanical separation many polymers still contain 30-60 weight percent solvent. Consequently, […]
