| Abstract: | The chemical polymerizations of pyrrole in the presence of acetophenone and formaldehyde, cyclohexanone, acetaldehyde, and formaldehyde, cyclohexanone and formaldehyde, cyclohexanone, resorcinol, and formaldehyde, cyclohexanone and lignosulfonate formaldehyde, and cyclohexanone, pyrrole, and formaldehyde were accomplished with Ce(IV) salt in acetonitrile solutions. The roles of the resin type, the addition order of the reactants, and the concentrations of the pyrrole and resin on the solubility and conductivity of the resulting products were investigated. The cyclohexanone–acetaldehyde–formaldehyde resin/polypyrrole copolymer had the highest solubility in dimethylformamide. The conductivity and solubility of the copolymers could be controlled by the Ce(IV)/pyrrole/resin molar ratio. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 96: 618–624, 2005 |
