    Abstract: PURPOSE:To obtain a thiophene polymer composition which, when doped with anions, can show an electric conductivity sufficiently high for actual use, by electrolytically polymerizing thiophene or 3-methylthiophene in a specified condition. CONSTITUTION:Thiophene or 3-methylthiophene is electrolytically polymerized in a reaction system formed by dissolving thiophene or 3-methylthiophene and a supporting electrolyte containing hexafluorophosphate ions, hexafluoroarsenate ions, tetrafluoroborate ions, perchlorate ions or trifluoromethanesulfonate ions. In this way, a polymer composition comprising poly(2,5-thienylene) or poly[2,5-(3- methylthienylene)] doped with anions can be obtained. These polymer compositions have an electric conductivity of as high as 170-520S/cm.

    Abstract: PURPOSE:To simply obtain a polymer, having high electric conductivity, capable of carrying out oxidation and reduction and useful as an electrically conductive material, etc., for electronic parts by bringing a dialkoxy-bis (thienyl)silane into contact with iron chloride. CONSTITUTION:A dialkoxy-bis(2-thienyl)silane of formula I (R'' and R'' are alkyl) [e.g. diethoxybis(2-thienyl)silanel is brought into contact with iron(III) chloride to afford the objective polymer having a recurring unit of formula II. The reaction is preferably carried out at ambient temperature or a slightly heated temperature by dissolving the compound of formula I in an inert solvent and then adding iron(111) chloride powder to the resultant solution. This compound of formula I is preferably obtained by reacting a thiophene having the 2-position substituted with an alkali metal such as 2-lithiothiophene with a dihalodialkoxysilane used at 2:1 molar ratio in an inert solvent at -10 to $40 deg.C in an inert atmosphere.

    Abstract: NEW MATERIAL:A compound expressed by formula I ((n) is >=2). EXAMPLE:3-(3-Phenylpropyl)thiophene. USE:An organic electronic material. PREPARATION:A 3-halogenothiophene expressed by formula II (X is halogen) is allowed to react with a Grignard reagent expressed by formula III to provide a thiophene expressed by formula I, which is then subjected to oxidative polymerization or electrolytic polymerization to provide the polymer expressed by formula IV. The polymer expressed by formula IV is soluble in organic solvents and suitable as an organic conductive material having processability. Since the polymer expressed by formula IV has a regular head-to-tail structure, high functionality can be expected.

    Abstract: PURPOSE:To obtain the title polymer which dose not fade even when exposed to sunlight by dispersing fine particles of a noble metal in good efficiency in a high-molecular polymer, by dissolving a soluble salt of a noble metal in a liquid monomer, polymerizing the solution to form a solid and heat-treating this solid. CONSTITUTION:A soluble salt of a noble metal [e.g., chloroauric acid or sodium tetrachloropalladite] is dissolved in a liquid monomer (e.g., methyl methacrylate, styrene or isoprene), and the solution is polymerized to form a solid. This solid is heat-treated at a temperature higher than the temperature at which colloids of this noble metal can be formed. In this way, it is possible to disperse fine particles of a noble metal in good efficiency in a high-molecular polymer, so that a colored high-molecular polymer which is transparent, possesses a clear color tone such as red, yellow or brown, and does not fade even when exposed to sunlight for a long time outdoors can be obtained. This polymer can be suitably used for, e.g., decorative organic glass sheets, optical filters, and light- screening materials in the fields of buildings, optical devices and instruments, electrical appliances, sundries, etc.

    Abstract: PURPOSE:To obtain an organic conductor which can be widely applied in the field of electronics, by electrolytically polymerizing an organic conductor based on a specified organic polymer. CONSTITUTION:An organic conductor based on an organic polymer of the formula (wherein l is 1-6, m is 0-2, and R is a 1-6C linear alkyl, and n is 10-300) is produced by an electrolytic polymerization process comprising immersing a working electrode and a counter electrode in a solution formed by dissolving a polymerizable monomer such as an aromatic compound and a supporting electrolyte for applying a current in an organic solvent such as propylene carbonate, and applying a current across the electrodes. As the solvent, acetonitrile, propylene carbonate or nitrobenzene is particularly desirable. The polymerization temperature is preferably 0-10 deg.C, and the current density is preferably 1-55mA/cm . The polymerization is preferably carried out in a polymerization atmosphere of an inert gas such as nitrogen or argon.
