ABSTRACT:
A process is provided herein wherein a solid polymer slurry diluted with a specific diluent is continuously discharged under controlled conditions from a high pressure zone to a low pressure zone substantially maintained at atmospheric pressure and the slurry is then separated into said diluent and dried polymer, the improvement wherein the discharged amount of the solid polymer slurry is strictly controlled by varying the heat in the second zone and simultaneously adding a diluent which is gaseous under normal temperature and pressure so that by the control of these two perimeters a continuous slurry discharge can be maintained at predetermined levels.
