This invention discloses a devolatilization process for high melt flow index and high transparency lithium-based polymer solutions. The process employs falling film evaporation for initial evaporation, followed by deep devolatilization using a twin-screw extruder, with the volatile solvent being condensed and recovered. The devolatilized polymer melt is then extruded by a screw extruder, pelletized by an underwater pelletizer, and dehydrated by a centrifugal dewatering machine to obtain finished polymer granules. This method can be used for the devolatilization of high melt flow index, high transparency, and low water content lithium-based polymer solutions, and the resulting polymer volatile content is ≤0.5% (mass fraction). The granules or cobblestone-like particles are easy for downstream processing applications. This process is simple, low-cost, can be manufactured using existing mature equipment and processes, and is easy to control and industrialize.
