Amide derivatives of poly(3,4-dimethylenepyrrolidine): Synthesis, characterization, and complexation studies

Improved synthesis of polydiallylamine provides ready access to an entire family of amide‐functionalized polymers. Complete conversion to the acetamide derivative was attained under mild conditions. Formation of the formamide polymer required harsher conditions and did not give complete functionalization. The formamide polymer displayed typical polyelectrolyte behavior caused by residual amine units. Complexation with iodine and transition metal cations was strong as shown by UV, IR, and 13C‐NMR evidence indicating potential of these polymers for trace metal recovery, waste water treatment, and antiseptic formulations.
