Abstract—Stabilized polypyrrole dispersions were prepared by oxidative polymerization of pyrrole in aqueous
solution of polyvinyl alcohol. The inﬂ uence of the concentration and molecular mass of polyvinyl alcohol in the
reaction mixture on the size of the particles formed was examined, and the particle structure was determined. The
possibility of preparing hemocompatible ﬁ lms from aqueous polypyrrole dispersions stabilized with polyvinyl
alcohol was demonstrated.
Owing to the through conjugation along the chain,
polypyrrole exhibits electrical conductivity in the doped
state and activity in redox transformations. Therefore, it
has found use in molecular electronics and in production
of sensors and hemocompatible materials [1, 2]. Polypyr-
role is prepared by oxidative polymerization of pyrrole,
occurring under normal conditions in aqueous medium
under the action of oxidants such as iron(III) chloride,
silver nitrate, and sodium and ammonium peroxodisul-
fates [1, 3, 4].
Despite simplicity of polypyrrole preparation, its use is
limited by problems with processing, associated with its
infusibility and insolubility in any of the known solvents
problems because of the presence of cross-links [5–7].
Therefore, polypyrrole is applied onto the surface
of various materials by chemical  or electrochemical
[9, 10] polymerization. An alternative procedure of
polypyrrole processing consists in synthesis of its
