Solvent removal from polymer solutions |
摘要 |
By cooling the barrel of a devolatilizing extruder rather than by heating it, both the solvent removal rate and the polymer feed rate could be increased; furthermore, the power surging of the motor driving the extruder was largely reduced or even eliminated by the process of this invention.
