Blending Of Immiscible Polymers In A Mixing Zone Of A Twin Screw Extruder- Effects Of Compatibilization, William Macknight, O. Franzheim, T. Rische, M. Stephan
William MacKnight
The dependence of the morphology development of physical as well as of reactive
compatibilized polypropylene/polyamide 6 (PP /PA6) blends in a mixing zone of a
co-rotating twin screw extruder on blend composition and screw rotational speed
was investigated. A special process analytical set-up based on a co-rotating twin
screw extruder was used, which allowed melt sampling from different positions
along the operating extruder in time periods less than 10 seconds. It has been
shown that the disperse particle sizes in physical blends depend crucially on the
blend composition because of the increasing influence of coalescence with an increasing
concentration of …
