✦ Synopsis

In order to calculate some kinetic parameters, such as the reactivity ratios, of the system ␣-methylstyrene-methyl methacrylate, the bulk copolymerization of these two monomers with azobis isobutironitrile (AIBN) as a radical initiator was studied. Experiments were performed at the various temperatures of 50, 60, and 80°C with 0.5 mol % of initiator (AIBN). The kinetics, molecular weights, microstructure, and glass transition temperature (T g ) of the copolymers were followed. A software, previously developed (part I), taking into account the equilibrium of the homopolymerization of ␣-methylstyrene, was used to simulate the experimental data. The model was in good agreement with all the experimental data.
