| Abstract: | The exothermic curve of SMI heat resistant modifier at initial stage of polymerization reaction was presented, and characteristics of the reaction were pointed out. The critical parameters including Pv , Np/Nqd and coefficient of heat transfer were studied in a 150 L polymerization reactor. And the result in laboratory could be reappeared in the reactor. The heat transfer calculated by empirical formula was verified by water transport experiment, the actual value was consistent with the theoretical value successfully, and the controllability of the polymerization reaction was realized. The results could provide reference for further amplification study. |
