摘要：Polyetherimides are formed by the blending of a first melt of organic

dianhydride and a second melt of organic diamine and the resulting blend is polymerizedin a continuous, steady state manner, employing an extruder reactor as the reactionchamber. The extruder reactor is provided with means for heating, evacuation of water ofreaction, and transfer sections in order to achieve the steady state necessary forcontinuous production of a substantially uniform polyimide.
