Abstract

Aniline was polymerised at temperatures of between 0 and -35 degrees C
in acid solution containing lithium chloride and using dichromate
oxidant. The optimum temperature to give high molecular weight
polyaniline in the emeraldine oxidation state in good yield was found
to be -22 +/- 3 degrees C. A solvent cast polyaniline camphorsulfonate
film was uniaxially stressed to give a conductivity of 848 +/- 70
Scm(-1) along the stretch direction and 118 +/- 10 Scm(-1)
perpendicular to this.
