A method for the production of soluble, ions - doped alkyl substituted polypyrroles

摘要

PURPOSE: To obtain an alkylated polypyrrole sol. in tetrahydrofuran, etc., and excellent in moldability by polymerizing an alkylated pyrrole in an org. solvent in the presence of a ferric salt, adding water to the reaction system, and separating the resulting polymer. ;CONSTITUTION: An alkylated polypyrrole sol. in an org. solvent with a solubility parameter of 7-10 (e.g. tetrahydrofuran, benzene, or chloroform) is obtd. by chemically polymerizing 0.01-5mol of an alkylated pyrrole of the formula (wherein X is alkyl; and Y is alkyl or H) in 1l of an org. solvent in the presence of a ferric salt in a molar ratio to the alkylated pyrrole of 0.1-5, adding water to the reaction system, and separating the resulting polymer. As the solvent for the above polymn., there may be used an alcohol, tetrahydrofuran, acetone, etc., an alcohol being esp. pref. the obtd. polypyrrole can be molded advantageously as a conductive polymer.;COPYRIGHT: (C)1995,JPO
