It is known from the Patent literature that many water-soluble salts of copolymerizable acids can be copolymerized with water in soluble, polymerizable esters when the latter are dispersed as an aqueous emulsion. We have studied the copolymerization of methacrylate esters, especially methyl methacrylate, with sodium, methacrylate, the former being maintained in a fine particle size with the aid of a water-soluble colloid and rapid stirring. Results have been reproducible. Analytical methods have been worked out for each monomer in the presence of the other, in order to follow the course of the reaction. Several ratios of methyl methacrylate and sodium methacrylate have been investigated under semi-adiabatic conditions, using a persulfate as polymerization initiator. When the two monomers are polymerized together equimolecular ratios, there is a period of inhibition or retardation only in respect of the sodium methacrylate, but this can be avoided by adding methyl methacrylate to sodium
