The melting and deformation mechanisms of polystyrene (PS) and polypropylene (PP) blends were investigated through on-line visualization of the co-rotating twin-screw extrusion process. A sliding barrel technique was used to realize the on-line visualization with one glass window in the barrel. The axial temperature and pressure profiles along the screw channel were measured using the same sliding technique. Different melting mechanisms were found for the PP/PS (80:20) blend and PS/PP (80:20) blend.
