Abstract: The o/w microemulsion polymerizations and copolymerizations of butyl acrylate (BA), styrene (St), and acrylonitrile (AN) initiated by a water-soluble initiator in the presence and absence of additives were investigated. Polymerizations and copolymerizations show two distinct nonstationary rate regions. The addition of isopropanol (IPA) was found to decrease the rate of polymerization and the decrease was more pronounced in the copolymerization runs. The rate of polymerization and the rate of particle formation decrease with increasing acrylonitrile concentration. The BA/AN copolymer latexes were more stable than the AN/St ones.
