Semicontinuous Emulsion Copolymerization of Vinyl acetate and Butyl acrylate with Nonionic Surfactants (Triton X Series)

Abstract

Summary: In this study, the copolymerization of vinyl acetate (VAc) and butyl acrylate (BuA) in water semicontinuous emulsions made with the nonionic surfactants, Triton Xs, was studied as a function number of ethylene oxide (EO, X) and their concentrations. The copolymerization of VAc and BuA was initiated by peroxide at proper temperature in order to improve the efficiency of droplet nucleation and maintain the stability of the emulsion. The effects of EO's in the surfactant structure and surfactant concentration on latex colloidal and physicochemical properties were investigated.

Novel Synthesis Method and Characterization of Poly(vinyl acetate‐butyl acrylate) Latex Particles: Effect of Silanol‐Terminated Poly(dimethylsiloxane) Surfactant on the Seeded Emulsion Copolymerization

“…Emulsion polymers of vinyl acetate have widespread industrial application (i.e., exterior and interior architectural waterborne coatings, adhesives, and paints) which is due to their low risk of fire, toxicity and cost [1][2][3][4][5]. Vinyl acetate copolymerizes with butyl acrylate and produces useful latex for application in acrylic emulsion paints [6][7][8][9]. The performance properties of colloidal stability, thermal resistive coating, and control of particle morphology were also evaluated in emulsion polymerization [10][11][12][13][14][15][16][17][18][19][20][21].…”
