The microemulsion (ME) and conventional emulsion (CE) copolymerizations of methyl methacrylate (MMA) with acrylonitrile (AN) are carried out at 70°C by employing n ‐butyl cellosolve as cosurfactant along with sodium lauryl sulfate as surfactant in the reaction medium and potassium persulfate as initiator. The copolymers are characterized by FTIR, NMR, TG/DTA, and GPC techniques. The reactivity ratios are evaluated by employing Fineman‐Ross, Kellen‐Tüdös (K‐T), and Mayo‐Lewis integration methods. The K‐T method yields reactivity ratios, r MMA and r AN , for the ME copolymerization of MMA and AN of 1.06 ± 0.01 and 0.14 ± 0.01, and those for the CE copolymerization of MMA and AN are 2.19 ± 0.01 and 0.14 ± 0.01, respectively. © 2004 Wiley Periodicals, Inc.
