Perconjugated polymer salts a new concept for drug release

Perconjugated polymer salts were prepared from pyrrole and counterions by an electrochemical anodic oxidation process. The counterions, e.g. heparin, penicillin-monobactam, camphorsulfonic acid, are incorporated in the pyrrole polymers and can be specifically released. The preparation conditions, morphological structure and properties of the polymer salts are described.
