Continuous self-cleaning reactor process

Styrene is polymerized in two reactors. The first one is a self-cleaning reactor (Q-300) and the second one is a stirred tank reactor with a helical ribbon mixer (V-300) [11]. 

The catalyst components are fed to the reactors. Fresh styrene is fed only to the self-cleaning reactor. In the reactors, styrene is polymerized to SPS in

The third process is a continuous self-cleaning reactor process [5,8-10], In the self-cleaning reactor, low adhesion powders can be easily obtained under low SPS conversions. The heat transfer coefficient in the self-cleaning reactor is relatively high. Multiple reactors are necessary to achieve efficiency in the production scale.
