Semicontinuous miniemulsion terpolymerization: Effect of the operation conditions

The effect of solids content, initiator concentration, feed‐flow rate, and amount of cosurfactant on the kinetics of the high solids content, semicontinuous miniemulsion terpolymerization of butyl acrylate, methyl methacrylate, and vinyl acetate was studied. In addition, the effect of the operation variables on the feasibility of obtaining a 65 wt% solids content latex with low amount of coagulum was investigated. The operation variables studied were: (1) partition of the monomer between the initial charge and the feed, (2) type and concentration of emulsifier; (3) feed‐flow rate; and (4) sonication. © 1993 John Wiley & Sons, Inc.
