Microwave-assisted polymerization process: A way to design new, high molecular weight poly(arylimidazole)s

In this paper, the microwave-assisted synthesis of high molecular weight poly(arylimidazole)s is described. These polymers were obtained by a one-pot polycondensation reaction involving a bis-(alpha-diketone), an aromatic dialdehyde and ammonium acetate. Depending on the dialclehyde monomer, different poly(arylimidazole)s structures were synthesized. Structural characterization (H-1 and C-13 NMR), thermal properties (T-g, thermal stability) as well as a molecular weight determination of the polymers are reported. (c) 2008 Elsevier Ltd.
