Abstract: In this work we have shown that the new polymerization process catalyzed by Mag-H+ can be applied to the polymerization of the pyrrole derivatives with nitrobenzealdehyde. Was synthesized poly (2,5-diyl 2,4-dinitrobenzylidène pyrrole), poly (2,5-pyrrole -4-nitrobenzénaldéhyde) and poly (2,5-pyrrole-3-nitrobenzènaldhyde) with Mag-H+ . The polymerization is done in solution, heterogeneous catalyst. The return on the amount of Maghnite-H+ 10% compared to the mass [Pyrrole] / [Benzaldehyde] = 50/50 is present a good yield. The data of different analytical methods used in this study: UV-visible and IR allowed to prove the characteristic bands of the synthesized polymers. The synthesized polymers were deposited on glass substrates and characterized by electron microscopy Atomic Force Microscopy (AFM), scanning electron microscopy (SEM) and optical measurements (transmission, absorption). The optical measurements of PPDNB show that it is a semiconductor. The PPDNB, PPNB (4), PPNB (3) obtained are soluble in the organic solvent, chloroform, toluene, NMP, acetonitrile, acetone and insoluble in water and methanol.
