In a method for preparing polyaniline, aniline is polymerized in a reactor in a polymerization medium containing aniline and oxidant. The polymerization is performed in a reactor in which the ratio of the heat transfer surface to the reaction volume is at least 10/m, preferably at least 20/m. In the apparatus, the polymerization is performed in a tubular reactor by allowing a medium containing aniline and oxidant to flow in a mixed flow through the tubular reactor. The tubular reactor is equipped with static mixers, and there can be several tubular reactors in parallel.
