    Solidstate shear pulverization (SSSP), which relies on a modified twin screw extruder to process materials in the solid state, is designed to overcome these limitations. Repeated fragmentation and fusion steps accompanying SSSP lead to intimate mixing and compatibilization which are difficult to be achieved in conventional melt mixing.

    Radical coupling is often referred to as a diffusioncontrolled reaction as it lacks an activation barrier to reaction. However, pulverization can lead both to intimate mixing, creating large interfacial area between blend components, and to chain scission, yielding polymer radicals and accommodating interpolymer coupling in the solid state.
