Kinetics of continuous addition emulsion polymerization

摘要

AbstractAn 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 additionRais constant. In the steady state, the rate of polymerization depends onRaaccording to a reciprocal relationship, 1/Rp= (1/K) + (1/Ra), whereKdepends on the number of particles and the propagation rate constant. Above a critical value ofRa, the particles will become saturated with monomer andRpwill be constant and independent o
