Studies on emulsifier-free emulsion polymerization using emulsifierable reactive monomer AGES

In this article, allylglycerdyl ether sulfosalt(AGES), a novel copolymeriza ble monomer containing not only the reactive vinyl bond, but also groups of sulforous and hydroxyl having the role of emulsifier was synthesized and u sed in the MMA/BA emulsifier-free emulsion polymerization, Particle size an d flowing behavior of the latexes, as well as dy namic mechanical propertie s of the resulted copolymers were investigated. The results show that with the addition of AGES, the latex particles are about 0. 5 mu m in diameter a nd are evenly distributed; stable latexes of high solid content(60%), low v iscosity with the characteristic of plastic Non-Newton flowing behavior is obtained, In addition, all the polymerization systems undergo a typical ran dom copolymerization.
