标题:Electrochemical synthesis of electrically conductive polymers and products thereof
发明人：KINLEN PATRICK J
权利人:ZIPPERLING KESSLER & CO
摘要:The electrochemical synthesis of electrically conductive polyaniline salts is provided. The method comprises electrochemical oxidation of an aromatic heterocyclic or aniline monomer oxidatively polymerizable to an intrinsically conductive polymer in the presence of water, an organic acid and, optionally, an organic solvent and an electron transfer mediator. Depending upon the water solubility of the organic acid, ICP salts soluble in either water or xylenes are produced.

摘要:The present invention relates to an improved synthesis method for the making of citraconimides wherein a citraconic anhydride is reacted with 0.5 to 2.0 equivalents of at least one amine salt. This process may be carried out in a solvent and generally leads to excellent yields of the citraconimides with high selectivity and easy purification. The present inventional so relates to a process for the production of citraconic anhydride from itaconic anhydride with an amine or phosphine catalyst and in a cosolvent.

标题:Synthesis of oligoarylamines, and uses and reagents related thereto

摘要:The transition metal-catalyzed amination of aryl halides, in conjunction with an orthogonal protective group scheme, forms the basis of two routes to oligoaniline precursors. The oligoaniline precursors are soluble in a variety of common organic solvents, and are easily converted to the deprotected oligoanilines. The method allows the preparation of oligoanilines of even or odd chain lengths, and the incorporation of a variety of functional groups into the oligomers. Polyanilines of low polydispersity can also be prepared by this method.

摘要:An process of forming a chiral conducting polymer, e.g., polyaniline, is provided including reacting a monomer, e.g., an aniline monomer, in the presence of a chiral dopant acid to produce a first reaction mixture by addition of a solution including a first portion of an oxidizing agent, the first portion of oxidizing agent characterized as insufficient to allow complete reaction of the monomer, and further reacting the first reaction mixture in the presence of the chiral dopant acid by addition of a solution including a second portion of the oxidizing agent, the second portion of oxidizing agent characterized as insufficient to allow complete reaction of the monomer, and repeating the reaction by addition of further portions of the oxidizing agent until the monomer reaction is complete to produce a chiral conducting polymer, e.g., polyaniline. A preferred process includes addition of a catalyst during the reaction, the catalyst selected from among the group consisting of phenylene diamine, aniline oligomers and amino-capped aniline oligomers and metal salts. n The processes of the present invention further provide a resultant polyaniline product having a chirality level defined by a molar ellipticity of from about 40×10 3 degree-cm 2 /decimole to about 700×10 3 degree-cm 2 /decimole. The processes of the present invention further provide a resultant polyaniline product having a nanofiber structure with a diameter of from about 30 nanometers to about 120 nanometers and from about 1 micron to about 5 microns in length.
