An analysis of the kinetics of continuous addition emulsion polymerization is presented. For systems that follow the Smith‐Ewart mechanism, this analysis predicts that the reaction will approach a steady‐state condition if the rate of monomer addition R a is constant. In the steady state, the rate of polymerization depends on R a according to a reciprocal relationship, 1/ R p = (1/ K ) + (1/ R a ), where K depends on the number of particles and the propagation rate constant. Above a critical value of R a , the particles will become saturated with monomer and R p will be constant and independent of R a .
