Phenylenediamines were polymerized using hydrogen peroxide as an oxidant in reversed micelles which were composed of sodium bis(2‐ethylhexyl)sulfosuccinate and water in isooctane. The spectroscopic analyses suggested that polymers of o ‐ and p ‐phenylenediamines retain the structure of disubstituted benzene nuclei of the monomers, indicating that the polymers are formed mainly via NN coupling. In contrast, m ‐phenylenediamine yielded polymers with more complex structure, probably produced by NN and NC couplings. Circular dichroic (CD) spectra of horseradish peroxidase suggested that the enzyme retains its native‐like structure and exhibits catalytic activity for polymerization of o ‐ and m ‐phenylenediamines in the reversed micelles.
