It is demonstrated that aromatic polyimine obtained by the condensatio
n of p-phenylenediamine and terephtalaldehyde can be chemically doped
with heteropolyanions of Keggin-type. The spectroscopic studies show t
hat polyimine undergoes protonation. The structural identity of the Ke
ggin units are preserved upon incorporation into the polymer matrix.
