Abstract
The steady state and dynamic behavior of a continuous stirred tank reactor has been analyzed for free radical solution polymerization of styrene initiated by a mixture of two initiators having different thermal stabilities. From the steady state analysis of the reactor model with a mean residence time as a bifurcation parameter, four unique regions of steady state solutions are identified in an operating parameter space for a given initiator feed composition. A variety of complex bifurcation behavior such as multiple steady states, Hopf bifurcation and limit cycles have been observed and their stability characteristics have been analyzed. The effects of feed initiator composition and the concentration of the initiator in the feed stream on the reactor dynamics are also presented.

## Abstract Microemulsions of styrene were polymerized using pulsed UV lasers. Molecular weights of the polystyrene produced were linearly dependent on the time interval between pulses when the number of photons absorbed per mL of microemulsion was ca. 5 Γ 10^15^. In contrast, laser pulses with muc
