摘要：A method of separating a polymer-solvent mixture is described wherein apolymer-solvent mixture is heated prior to its introduction into an extruder comprisingan upstream vent and/or a side feeder vent to allow flash evaporation of the solvent, anddownstream vents for removal of remaining solvent. The one-step method is highlyefficient having very high throughput rates while at the same time providing a polymerproduct containing low levels of residual solvent.
