Abstract

The control of particle size distribution (PSD) in semi-batch emulsion polymerization necessitates the identification of the best manipulative variables, with a profound influence on the PSD. The candidate variables include the feed rate of the monomers, surfactants and initiators. The monomer feed predominantly affects the growth rate, but could also influence nucleation rates. The surfactant feed influences the rates of nucleation and coagulation. The initiator feed could influence the rates of nucleation and growth. This paper describes the effect of these manipulative variables on the evolution of PSD, as studied in an experimental reactor system
