Emulsion Polymerization of Vinyl Acetate in the Presence of a New Cationic Surfactant

Abstract

In this study, the emulsion homopolymerization system containing vinyl acetate, potassium persulfate, a new cationic polymeric surfactant and water was studied by the applying semi-continuous emulsion polymerization process. The effects of new polymeric emulsifier on the physicochemical properties of obtained vinyl acetate latexes were investigated depending on vinyl acetate percentage in the polymerization recipe, and two thermal initiators in homopolymerization.

Emulsion Polymerization of Poly(Methacrylic Acid) Nanoparticles: Effects of Different Cationic Surfactants

“…Even though, cationic surfactant is not excellent foaming agent like anionic surfactant but they can exhibit positive charge that allow them to absorb negatively charged particles. Sarac et al [16] have developed emulsion polymerization of vinyl acetate in the presence of a new cationic polymer surfactant. The effect of new cationic polymeric surfactant and two thermal initiators on the physiochemical properties of a semi-continuous cationic emulsion polymerization of vinyl acetate have been studied.…”
