Synthesis, Characterization, and Kinetic Study of Poly(2-formyl pyrrole)

2-Formyl pyrrole polymerizes in alcoholic solution by hydrochloric acid as a catalyst. The polymeric product was characterized by FTIR, XPS, and EDX techniques, which confirmed that polymerization occurred through aldehyde group. Kinetics of the reaction was studied by UV–Vis absorption spectroscopy at 475 nm. It was found that reaction occurred according to an accelerated chain polymerization mechanism via two stages. Firstly, active centers are formed. Then the chain growth occurs. The reaction order with respect to monomer and catalyst concentration as well as reaction rate coefficients were determined on both stages. Suggested reaction mechanism is consistent with experimental data.
