ABSTRACT:
A process and apparatus for single screw solid state shear extrusion pulverization of polymeric materials in which the polymeric materials are heated to a temperature suitable for forming a continuous thin film of said polymeric material, and then cooled, and normal and shear forces sufficient to form powder of the polymeric material are applied by a single cylindrical or conical mesh screw. The resulting powder is fluidized upon its discharge.
