Abstract

Arylsulfinic acids such as benzenesulfinic acid (BSA) initiated the polymerization of methyl methacrylate (MMA) without oxidizing agents. Hydroquinone and 1,1-diphenyl-2-picrylhydrazyl had no inhibitory effecton the polymerization, indicating that the polymerization proceeded via a non-radical process. The rate of polymerization was found to be proportional to [BSA](0.98) and [MMA](0.99). The polymerization was greater in less polar solvents than in polar solvents. On the basis of the experimental results obtained, an ionic mechanism was proposed, in which a Michael-type addition of the arylsulfinic acid to MMA leads to the polymerization.
