Abstract

Methyl methacrylate(MMA) and methylacrylic acid (MAA) can form the contact charge transfer complex(CCT) with O₂, respectively. After O₂ was bubbled, the concentration of hydroperoxide in MMA increased with the increasing of oxidation time, however, it did not increase in MAA. From the IR, NMR spectra, it showed that the initial oxidation occured on the α-methyl group of MMA and MAA molecules via MMA-O₂ CCT and MAA-O₂ CCT, respectively. In the case of MAA, the hydroperoxide group would further decompose and produce an aldehyde group.
