(57) Summary: [Objective] To obtain a conductive polymer whose acidity is substantially reduced and whose conductivity level is sufficiently high, and which is suitable for melt processing in, for example, a conventional plastics processing apparatus. [Structure] (a) 1 to 20% by weight of polyaniline or a derivative thereof and dodecyl benzene acid calculated as ~ 90 wt% protic doping acid, and 1 to 45 Making a mixture consisting of wt% water and / or a component which is a C 1 -C 3 alcohol, and (b) said step (a) The mixture obtained in 1. is fed to a mixing device and sheared to produce 5 Mixing at a temperature of 0-400 ° C., (c) recovering the blend obtained from step (b) from the melt-mixing device, and (d) further blending the blend collected in step (c). Consists of processing. |
