摘要： A simple chemical process for the simultaneous polymerization and oxidation of pyrrole, N-substituted pyrroles, and other heterocycles having five or six member rings by halogenic or organic electron acceptors. The polypyrrole-acceptor charge transfer complexes so produced are of high purity and are stable in the atmosphere, in the presence of moisture and at elevated temperatures. The conductivities of the complexes are controllable between 30 ohm.sup.-1 cm.sup.-1 and 10.sup.-3 ohm-1 cm-1, depending on the type of acceptor used and the process conditions.

摘要： The present invention is directed to a process for reducing the oxidation state of a metal by contacting an acidic solution of the metal with an electroactive polymer, and accumulating and recovering the metal. More particularly, the invention is directed to a method for recovering precious metals like gold, platinum, palladium, and gold-platinum alloys from acidic solution by contacting the solution with an electroactive polymer like polyaniline or polypyrrole.
