Controlled/living radical copolymerization of vinyl acetate and dibutyl maleate was achieved by a degenerative transfer process using alkyl iodides as transfer agents. Controlled characteristic of the reaction is investigated by 1H-NMR and GPC analyses. 1H-NMR spectroscopy is also used to evaluate monomer conversion and copolymer composition. A relatively narrow molecular weight distribution with a good agreement between the theoretical and experimental molecular weights was observed, indicating that copolymerization of VAc and DBM proceeds via the controlled characteristic
