ABSTRACT:
Preparation of conductive polymers, particularly polyanilines having good solubility in organic solvents and high electrical conductivity, by providing a mixture of aniline, dianiline and a flexible diamine such as 1,3-bis (3-aminophenoxy)benzene or triethylene tetramine. The mixture is reacted in the presence of an oxidant such as ammonium persulfate and a protonic (Bronsted) acid, e.g. tosic acid, to polymerize the mixture and form a conductive polyaniline in which the conjugation is interrupted by an intermediate diamine group, and which renders the resulting polymer more flexible than polyaniline per se. The conductive polymer so produced also has terminal primary amino groups which aid solubility and which are further reactive. The conductive polyaniline product of the invention can be blended with non-conductive resins such as polyimides to provide cured conductive resin blends having good mechanical properties.
