Abstract

Solid-state shear pulverization is a unique, emerging processing technique for mechanochemical modification of polymers, compatibilization of polymer blends, and dispersion of fillers in polymer composites. The instrumentation is a modified twin-screw extruder, where the barrels are continuously cooled below the transition temperatures of polymers. Using neat polypropylene, the effects of various processing parameters, such as barrel dimensions and temperature, screw design, and material throughtput, are correlated to output morphology, structure and properties.
