Abstract: The present disclosure relates to extrusion processes. In at least one embodiment, a method of forming a functionalized polymer includes introducing a polymer and a coupling agent to an extruder at a feed throat of the extruder. The method includes extruding the polymer and the coupling agent through at least a portion of the extruder via a plurality of intermeshing screws disposed within the extruder to form the functionalized polymer. The at least one screw of the plurality of intermeshing screws has a first mixing zone having a total length of about 4 L/D to about 6 L/D, a second mixing zone having a total length of 2.5 L/D to 3.5 L/D, and a third mixing zone having a total length of about 2.5 L/D to about 4.5 L/D.

Abstract: The present disclosure relates to a method of forming a composition including forming a polymer melt in a melt feeder. The melt feeder is coupled with an extruder. The method includes introducing the polymer melt from the melt feeder to the extruder at a first location of the extruder. The method includes extruding the polymer melt through the extruder via a plurality of intermeshing screws disposed within the extruder. The method includes introducing a coupling agent to the extruder at a second location of the extruder.
