Abstract: The influence of temperature on pHof system of emulsifier-free emulsion polymerization of styrene-butyl acrylate in the presence of sodium undecylenate is discussed.The curve of polymerization kinetics is described.The reaction rate constant(kP)at different temperatures is calculated.Using TEMto compare emulsion polymerization of several emulsifier system,we found that the homogeneity and adhesion and deformation of the particles of emulsion could be controlled.Because there are no free emulsifier,the stability of emulsion is raised.
