Divalent group 14 metal species, a germylene(la) and a stannylene(lb), behaved as a comonomer(reductant monomer) in the copolymerization with p‐benzoquinone derivatives(oxidant monomer)(“oxidation‐reduction copolymerization”) and as an initiator for anionic monomers. The copolymerization took place without initiator at a lower temperature to give an alternating copolymer. N‐phenyl‐p‐quinoneimine also behaved as a reactive oxidant monomer toward la and lb. These species have been shown to induce the polymerization of anionically polymerizable monomers such as methyl methacrylate, methacrylonitrile, and 4‐vinylpyridine. Based on the mechanistic examination of the polymerization, a new alternating copolymerization between la and 2‐cyclohexene‐l‐one has been developed to produce a copolymer having a metal‐enolate structure, which involves the oxidation‐reduction process during the copolymerization.
