Polymerization of Methyl Methacrylate Initiated by Cobalt () Nitrate

[摘要] The polymerization of methyl methacrylate(MMA) initiated by cobalt (¥±) nitrate in tetrahydrofuran (THF) has been studied. From the results of kinetic studies, the overall polymerization rate (Rp) could be expressed as following; Rp = k[cobalt(¥±) nitrate]0.5[MMA]1.5 By considering the effects of chelating agent on the polymerization rate, it could be assumed that the monomer, MMA might form a coordination complex with cobalt(¥±) nitrate. In the presence of radical inhibitor hydroquinone, the inhibition time was observed. And the apparent overall activation energy was calculated to be 14.0 kcal/mole.
