| titleOfInvention | Polyanilines and their manufacture |
| abstract | A polyaniline is characterised by a nuclear magnetic resonance spectrum in its leuco form showing only two <13>C peaks, indicating the substantal absence of chain branching and preferably by a molecular weight (Mp) above 90,000 and up to about 170,000 (more especially 100 - 140,000). Oriented films of such polyanilines in the protonated emeraldine oxidation state have electrical conductivities up to at least around 6000S/cm. They may be made by oxidising aniline in aqueous solution with a persulphate under the combination of conditions that the acidity of the solution throughout the reaction is such that if its temperature is adjusted to 20 DEG C it will have a pH in the range from about -0.2 to +3.0; that the temperature of the solution is in the range from -5 to about -40 DEG C; that the solution contains at least sufficient inert ionic solute to maintain it in the liquid state; and that the persulphate is added to the solution always at a rate corresponding to a total addition time of at least six hours (but preferably not over 36 hours) and in a molar ratio to the aniline in the range from 1.1:1 to 1.4:1. <IMAGE> |
