the minimum amount of emulsifier required to produce microemulsion were studied. It was found that there are obvious grafting effect of emulsifier in the process of radiation induce polymerization. The kinetics of radiahon induced microemulsion polymerization were studied with dilatometer and the intrinsic viscosity of the resulted polymer were determined with Ubbelode capillary viscometer. The results were as: In comparison with polyelectrolyte

the latex resulted from microemulsion polymerization is a special thickener with a good electrolyte resistibility and apoor surfactant resistibility.
