Abstract
The stability of continuous emulsion polymer reactors having steady feed streams was studied. Analysis of a population balance model supported the notion of micelle deprivation as the chief cause of reactor instabilities. Analysis of the moments of the distribution indicated that the system may be uniquely stable in one case. Only one steadyβstate operating point was predicted for the case where the decrease in the termination rate constant due to the gel effect was neglected.

## Experiments have been carried out using a continuous flow back-mixed emulsion polymerization reactor. Styrene was used as monomer. Particular attention was given to the effects of start-up procedure on reactor hehaviour. Steady feed rates were not always accompanied by steady conversions of mon
