Soluble Precursor Route to Polyanilines
Abstract
To achieve the fundamental goal of producing a processible form of the conducting polymer polyaniline (PANI), the Phase I program concentrated on development of the synthesis of a precursor polymer via the solution co- polymerization of bis(annellated)benzoquinone with p-phenylenediamine. The resulting polymer, expected to be soluble in common organic solvents, would be converted to PANI by thermal elimination of the pendant cyclopentadiene groups following processing. Attempts to carry out the proposed polymerization reaction using conventional methods for ketone-amine condensation were not successful, and resulted in the conclusion that bis(annellated)benzoquinone is too 'crowded' a ketone for the polycondensation chemistry. Simultaneously, through another line of research (motivated by the desire to produce a melt processible form of PANI which is compatible with other bulk polymers such as, e.g., polyolefins, PVC, nylon, Polystyrene, etc.).
