Abstract

Abstract: The critical micelle concentration(CMC) of sodium dodecyl sulfate(SDS),alklphenol ethoxylates(OP-10) and composite emulsifiers were determined using fluorescence probe technique.The polymerization of organosilion-acrylate core-shell emulsion was studied by using this technique for the first time.The effect of emulsifier’s micellization in the polymerization of organosilion-acrylate core-shell emulsion was discussed by the I₁/I₃ values of pyrene and the variation of polarity of micelle micro-environment and emulsion polymerization mechanism.It is suggested that the fluorescence probe(pyrene) technique can be used to study the polymerization process of organosilion-acrylate core-shell emulsion and the determination of optimal emulsifier ratio.The properties of the emulsion were characterized by particle size analysis、transmission electron microscope(TEM).

Key words: florescence probe technique, emulsifier, CMC, organosilion-acrylate core-shell emulsion
