Statistical copolymerizations have been performed for three binary systems using initiation by a typical "group-transfer" initiator/catalyst combination. The monomer pairs concerned are (i) methyl methacrylate (MM) and ethyl methacrylate (EM), (ii) MM and methacrylonitrile (MAN), and (iii) EM and MAN. The reactivity ratios determined in this study are: (i) r(MM) = 1.58, r(EM) = 0.40; (ii) r(MM) = 0.12, r(MAN) = 2.69; and (iii) r(EM) = 0.16, r(MAN) = 3.75.
