Poly(glycidyl methacrylate) latices were prepared in the absence of any emulsifier using potassium persulfate as an initiator. The average particle size distribution(standard deviation) of each dried latex were determined by the scanning electron microscope. It was found that the particle diameter increased with the increase of initiator concentration and initial monomer concentration and that the particles had high monodispersity. The stability of these 1atex dispersions against potassium chloride was investigated using sedimentation method. The stability increased with the initiator concentration and the initial monomer concentration. It was observed from the kinetics of polymerization that the polymerization rate increased wi th the increase of initiator concentration the initial monomer concentration and temperature. Reaction of poly (glycidyl methacrylate) latices with ammonium hydroxide and diethanol amino led to essentially complete conversion of epoxy groups, but that with piperazine took place to the surface of latex.
