Abstract Solid-state shear pulverization (SSSP) is an innovative, continuous, environmentally benign, and industrially scalable process used to make materials that cannot be made via conventional processing techniques, reduce material cost by eliminating processing steps, and/or produce materials with superior properties as a result of better break-up and dispersion of

Self‐compatibilization of polymer blends via novel solid

The mechanochemistry of a novel economical solid‐state shear extrusion (SSSE) pulverization is investigated. SSSE compatibilizes incompatible blends in situ; the process has great potential in recycling of post‐consumer plastic waste (PCPW). It is proposed that SSSE causes this self‐compatibilization of blends by rupturing polymer chains and allowing them to recombine
