This reactor is usually used in the continuous polymerization process of spandex. Compared with the traditional intermittent polymerization process, the continuous polymerization process can provide more uniform product quality, simplify the production process, reduce energy consumption, and improve production efficiency.

[0021] Beneficial Effects

[0022] The present invention provides a polymerization reactor for continuous production of spandex and a polymerization reaction method thereof. Compared with the prior art, it has the following beneficial effects:

[0023] (1) The reactor can drive the first rotating rod to rotate through the motor, driving rod, first gear and second gear, thereby driving the stirring wheel to rotate, and the flip rod is rotatably connected to the side wall of the circular block, and one end of the flip rod extends into the first annular groove.
