Abstract Single-electron transfer controlled radical polymerization (SET-CRP) is one of promising synthetic method for functional polymers with controlled molecular weight, dispersity, and end-group functionalities. It is known that typically, kinetics of controlled radical polymerization (CRP) follows first-order reaction. Although the mechanism of SET-LRP seems similar to that of typical CRP, it needs further studies in aspect of kinetics as the fundamental of polymerization mechanism has still distinctions. For example, disproportionation mechanism can distinctively exist in SET-CRP to regenerate Cu(0) for catalyst precursor. Also, copolymerization via SET-CRP is not thoroughly studied yet, which is extremely important for its expansion to a number of applications. Herein, We demonstrate the kinetic studies of copolymerization of pairs of unfunctionalizable methacrylate and various functionalizable methacrylates. We found that SET-LRP also follows first-order kinetics by examining the monomer conversion as a function of reaction time. These fundamental results elucidate how the copolymerization via SET-LRP differs from other polymerization methods in terms of the tendency for composition drifts of resulting copolymers.
