Free‐radical copolymerization at 50°C of butyl acrylate with methyl methacrylate was carried out in benzene solution using 3 and 5 mol/L as the overall concentration of monomers. Both the reactivity ratios and the rate coefficients of copolymerization are affected by the total monomer concentration. Reactivity ratios were analyzed on the basis of the “bootstrap” model, and the copolymerization rate is interpreted assuming a penultimate effect upon the propagation reaction.
