Copolymerization of methacrylamide and methyl methacrylate in dimethylfor- mamide initiated by the redox system CNCH,COOH/Mn(OAC), and AIBN has been investigated at the temperatures 35 and 60° respectively. The data on reactivity ratios are compared with those of other monomer pairs involvlna methacrylyamide and the values obtained using AIBN as the Initiator are presented. The mean sequence lengths (ñ) in the formation of various structural units were estimated for these copolymers.
