ABSTRACT:
A method for preparing a polyaniline having a desired molar mass. Control of the molar mass of the polyaniline is achieved in connection with an aniline polymerization reaction, by feeding aniline and an oxidizing agent participating in the polymerization reaction gradually into a polymerization vessel. By varying the feeding speeds of the aniline and the oxidizing agent, polyanilines having different molar masses are obtained.
