Polycondensation condensation coordination

Polycondensates with the Ligand as a Comonomer. Metal-bearing polycondensates in which the ligand moiety alone or in combination with the coordinated metal ions form one of the backbone comonomers are exemplified by the following polymers reported by Wudl et al [48], Biswas and Mazumdar [49, 50] and by Takahashi et al. [51] in the synthesis of organotin polymer by a similar condensate (Figs. 20, 21).
