Transcribed Image Text:

The kinetics of the polymerization of methyl methacrylate monomer were studied at 77 C using benzene as a solvent and azo-bisisobutylronitrile (AIBN) as the free radical initiator. The following contains some data from an ideal batch reactor that shows the initial rate of reaction, TM, as a function of the initial concentration of monomer, [M], and the initial concentration of initiator, [1].
