In order to gain a better understanding of propylene oxide polymerization process and to provide a theoretical basis for domestic production operations. In this paper, according to the characteristics of polymerizer, the reaction kinetic equation of polyether plant was first deduced by studying the polymerization mechanism of propylene oxide and the kinetics of chain link. Secondly, the mathematical model of propylene oxide polymerization was established to realize real-time dynamic simulation of polymerization process. Finally, the effects of the operating conditions on the average molecular weight and the double bond are discussed based on the simulation results. The actual production has a certain significance.
