Abstract:
The invention generally relates to an extruder (10) for preparing a mixture of polymer and diluent. The extruder includes multiple extruder stages, the multiple extruder stages comprising an inlet stage (1100), a dispersion stage (1200), and at least one mixing stage (1300,1400) comprising a reverse mixing screw segment (1406) having a helical flight (1306) that traverses and forms an outer periphery thereof, the helical flight having a plurality of notches (1308) positioned there along. A process for extruding the polymer-diluent mixture is also provided.
