Polymer Processing Operations Other Than Shaping
Polymer processing operations which do not involve shaping are defined here as those which are concerned with the synthesis of high molecular weight polymers, and those which are concerned with affecting physico-chemical changes in the nature of polymeric materials. These operations, which are most often conducted upstream from the shaping operations (i.e., extrusion, injection molding, blow molding, tubular film blowing, fiber spinning), include by way of example: vapor-liquid stripping operations when the liquid phase is a molten polymer or polymer solution (devolatilization), liquid-liquid stripping operations where one liquid is a molten polymer or polymeric solution, gas absorption in molten polymers, polymerization and grafting reactions, mixing, pumping and pressurization, and filtration.
