"Research progress in equipment and technology of intendifying polymer devolatilization"

Abstract

The transfer mechanism and process characteristics of polymer devolatilization were briefly described， and the mechanism and process intensification of devolatilization mass transfer were introduced. The methods of polymer devolatilization process intensification were summarized from the devolatilization equipment and devolatilization process， and it was pointed out that the new devolatilization equipment and process were the key to realize the high-efficiency devolatilization of polymer. The research status and development trend of new technologies of polymer devolatilization， such as supercritical fluid， ultrasonic cavitation and high gravity were emphatically expounded with 62 refe-rences.
