The kinetics of the atom‐transfer radical polymerization (ATRP) of dimethyl itaconate (DMI) are discussed. DMI polymerizations were carried out using a CuX/2,2′‐bipyridine catalytic system (X = Cl, Br) and a variety of initiators. The polymerizations exhibited a linear dependence of monomer consumption versus time, up to approximately 50% conversion. A linear increase of number‐average molecular weight ( M̄ w ) versus monomer conversion was observed. The close correlation of the theoretical molecular weight ( M̄ n,th ) with that determined from size exclusion chromatography ( M̄ n,SEC ) indicates that these systems have an efficient initiator, and that the number of active chains remains constant during the polymerization. Thermal properties of the polymers synthesized were evaluated and compared to those prepared by conventional free radical polymerization.
