Polymerization runaway stage

Recently, we have been studying the runaway stages of some polymerization reactions. We are trying to learn more about designing equipment safely in the event a reaction gets out of control and runs away. [Pg.339]

Like many other exothermic reactions in stirred tanks, three steady stages are possible for polymerizations beginning with monomer a lower one where there is essentially zero conversion an intermediate, metastable condition and an upper, runaway condition where conversion to polymer is nearly complete. It is usually desired to operate at the intermediate, metastable condition. To illustrate this, assume that the polymerization kinetics are pseudo-first order and write material and energy balances based on perfect mixing in the reactor. A material balance on monomer gives... [Pg.145]
