Emulsion Polymerization of Methyl Methacrylate and Butyl Acrylate Using Non-Ionic Polyurethane as Emulsifier

Article Preview

Abstract:

In this paper, non-ionic polyurethane surfactant which has real good surface activity and better emulsifying capability was totally substitute low molecular weight surfactant for preparing polyacrylate emulsion without any other stabilizer. Kinetics of polymerization was studied and the results showed polymerization with a high rate in initial period and nucleation period was is inversely proportional to the surfactant concentration. The morphology of particles was sphere with core-shell structure. Mechanical testing results shows latex film composed with PUS IGM2000 is better than the one with PUS IGM1000.
