ABSTRACT:
Coated polymeric material is sized and fed into an extruder. The material is cooled to maintain the temperature of the polymeric material below its melt index. The shearing action of the extruder separates the coating material from the polymeric material. The discharge from the extruder is polymeric material and coating material. These materials are separated and recovered.
