The manganic hydroxide–hydrazine system as an initiator of vinyl polymerization. III. The emulsion polymerization of methyl methacrylate

Emulsion polymerization of methyl methacrylate with the manganic hydroxide–hydrazine system has been studied. An attempt was made to corroborate earlier evidence that the initiation may involve a surface reaction on an insoluble manganese compound. The surface area of the manganic hydroxide was varied, and the effect of this variation on the rate of decomposition of hydrazine was examined. A correlation was found between the polymerization rate and the surface area of the precipitate.
