Abstract The kinetics of the copolymerisation of methylmethacrylate and maleic anhydride have been examined at 60°C. The reactivity ratios have been determined by analytical and radioactive techniques and are r 1 = 3.5 and r 2 = 0.03. Radioactive azoisobutyronitrile has been used as initiator; the rate and efficiency of the process have been detemined. The reaction follows a normal course with termination by radical‐radical interactions. The unusual feature is the increase of rate with increasing proportion of maleic anhydride. This is not in accordance with copolymerisation theory.
