Methyl methacrylate MMA whose structure is shown in Fig. 2.10 belongs to the C s point group. It has a twofold reaction path degeneracy due to its two equivalent faces which can be attacked by the propagating radical. Moreover MMA has two isomers scis and strans as defined by rotation around the single bond of the methacrylate group.Our estimates suggested that the s
