Methyl methacrylate was copolymerized with butyl or isobutyl acrylates, and butyl, isobutyl, or 2,3-epoxypropyl methacrylates, by hydrogen peroxide, in the presence of ethanol under UV irradiation (at 254 nm) at room temperature. The analysis of the microstructures was based on resonance splitting of the methoxy protons of MMA, depending on their environment. This splitting was not obtained with isobutyl and 2,3-epoxypropyl methacrylates. All the products were found to be predominantly syndiotactic.

Methylmethacrylate (MMA) was polymerized in an oxygen or argon atmoq --:re with utyl or isobutyl acrylates, and butyl, isobutyl, or 2,3-epoxypropyl methacrylates, by hydrogen peroxyde in the presence of ethanol under UV irradiation (254 nm) at room temperature. The reactivity ratios were determined. MMA shows a higher reactivity than its comonomers, in good agreement with the results of the literature, except for isobutyl and 2,3-epoxypropyl methacrylates.
