Abstract

Abstract: The kinetic behavior of aniline(An) emulsion polymerization using ammonium persulfate(APS) as the initiator in the presence and absence of a constant magnetic field(MF) was discussed via the quartz crystal microbalance(QCM) technique. The experimental results indicate that the reaction rate exhibited first-order with respect to aniline and half-order to APS and dodecylbenzene sulfonic acid(DBSA). The aniline polymerization rate in the presence of a MF was higher than that of aniline polymerization in the absence of a MF. The activation energy obtained under the two conditions were 40.4 and 41.6 kJ/mol, respectively. It is suggested that the QCM technique can provide an efficient way for the kinetic research of An polymerization.
