This article reviews our current work on the palladium‐ and nickel‐catalyzed polycondensations for the synthesis of various types of condensation polymers. We succeeded for the first time in the synthesis of carbon‐carbon coupling polymers, that is polycinnamamides, by the palladium‐catalyzed cross‐coupling polycondensation of aromatic diiodides with divinylic compounds. We further developed a new promising method of the synthesis of aramids and related condensation polymers by the palladium‐catalyzed carbonylation polycondensation starting from aromatic dibromides, bifunctional nucleophilic monomers such as aromatic diamines, and carbon monoxide.
