Copolymerizations of methyl methacrylate (MMA) and butyl acrylate (BA) have been performed using different monomer feed compositions in the presence of the chain‐transfer agent dodecanethiol (DDT) at 60°C in benzene solution. The average chain‐transfer constants as a function of the monomer feed composition were determined by using the conventional Mayo method and by the chain length distribution (CLD) procedure. The average chain‐transfer constants obtained from both methods are compared to model predictions based upon both the terminal and penultimate unit models of free‐radical copolymerization, and they are in satisfactory agreement with each other.
