摘要：
The nucleation mode of emulsion polymerization of styrene under different emulsifier (SDS) concentrations is studied in this paper. Some factors such as conversion, particle number (Np), fraction of coverage, polydispersion index (PDT) and particle size distribution (PSD) of the reactions were investigated. The results show that when [SDS] is less than its CMC, homogeneous nucleation dominates. But when [SDS] is more than its CMC, micelle nucleation plays the major role.
