ABSTRACT:
The invention relates to a conductive polymer complex which contains a polyaniline or derivative thereof doped with a protonic acid. By the method according to the invention, a conductive polymer is obtained having substantially reduced acidity, sufficiently high conductivity level, and which is suitable, for example, for being melt processed in conventional plastics processing apparatus. The acidity of the conductive polymer can be reduced by having the conductive polymer contain both a metal compound and an additionally neutralizing compound. The obtained conductive polymer material, having a pH value of approximately 3-8, can be mixed with an insulating polymer to produce a conductive plastics mixture. The invention also relates to a method of preparing a conductive polymer that is more processable by incorporating therein a plasticizing agent selected from the group consisting of water, a C.sub.1 -C.sub.3 alcohol, and mixtures thereof.
