Copolymerization of acrylonitrile (AN), methacrylonitrile (MAN), methyl vinyl ketone (MVK), methyl acrylate (MA), and methyl methacrylate (MMA), complexed by ethylaluminum dichloride, with isobutylene (IB), styrene (St), and vinyl acetate (VA) was studied. It was found to proceed spontaneously resulting alternating copolymers. The reactivity of the polar monomers complexed by EtAlCl2 in their copolymerization with St and IB was investigated and found to decrease in the following order: AN > MAN > MA > MMA and AN > MVK > MA, respectively, (MAN and MMA do not give copolymers with IB). A correlation of the copolymerization yield with the e value for the uncomplexed monomers investigated was observed.
