a continuous mixer having a mixing section selected from the group consisting dispersive mixers and/or distributive mixers; and an ultrasonic horn communicating with said continuous mixer.
- 2. An apparatus as in claim 1, wherein said continuous mixer is selected from the group consisting of single-screw extruders twin-screw extruders, and modular twin screw extruders.
- 3. An apparatus as in claim 2, wherein said ultrasonic horn communicates with said continuous mixer at the exit of said continuous mixer.
- 4. An apparatus as in claim 2, wherein said continuous mixer includes a die attachment and said ultrasonic horn communicates with said die attachment.
- 5. An apparatus for the production of polymer blends and copolymers comprising:
a twin-screw extruder; a pressurized treatment zone; and an ultrasonic horn communicating with said pressurized treatment zone.
- 6. An apparatus as in claim 5, wherein said pressurized treatment zone is provided at the exit of said twin-screw extruder, said ultrasonic horn being positioned proximate said exit.
- 7. An apparatus as in claim 5, further comprising a die attachment, said pressurized treatment zone being within said die attachment, and said ultrasonic horn communicating with said die attachment.
- 8. An apparatus as in claim 6, wherein said twin screw extruder is a modular twin screw extruder.
- 9. An apparatus for the production of polymer blends and copolymers comprising:
a batch mixer having at least one wall defining an interior of said batch mixer; an ultrasonic horn communicating with said interior through said at least one wall; rotors within said batch mixer and providing, upon the operation thereof, a pressurized zone proximate said ultrasonic horn.
- 10. An apparatus as in claim 9, wherein said batch mixer is selected from the group consisting of Banbury mixers, Farrel mixers, and Haake mixers.
