Novel polymerization reactions utilizing a divalent germanium or tin species, germylene or stannylene, have been developed. Copolymers having a germanium(IV) or tin(IV) unit in the main chain have been prepared by the reaction of oxidant monomers (Mox) and reductant monomers (Mred, germylene or stannylene). Oxidant monomers employed are p‐benzoquinones, N‐phenyl‐p‐quinoneimines, cyclic α, β‐ unsaturated ketones, and cyclic sulfides. A new aspect of these divalent chemical species as an initiator for vinyl monomers has also been investigated.
