  • High molecular weight polyanilines and synthetic methods therefor
    Patent number: 5519111
    Abstract: High molecular weight polyanilines are provided, alone with synthetic methods therefor. The methods generally comprise mixing aniline, protonic acid, salt, and a polymerization agent at the desired reaction temperature. The presence or the salt increases the molecular weight of the polyaniline produced. The reaction temperature is preferably maintained at lower temperatures to also increase the molecular weight of the polyaniline.
