Abstract
The polymerization of methyl methacrylate (MMA) by substituted benzoin—pyridine—Carbon tetrachloride system was carried out at 60°C. The electron-withdrawing substituent in benzoin accelerated the rate of polymerization, whereas the electron-donating groups decelerated it. Hammett plots gave a straight line with a ρ of 0.56. The rate of polymerization increased with an increase in the basicity of the amine but depended strongly on the steric effect. The effect of solvents on the rate of polymerization was found to be remarkable. On the basis of these results, the mechanism of initiation was discussed.
