Synthesis and characterization of some polyalkyl- and polyalkoxy-anilines

Abstract

Since poly-3-alkylthiophenes are more processible than polythiophene, it is expected that poly-<em>o</em>-alkyl and poly-<em>o</em>-alkoxyanilines will evince better processibility than polyaniline. Hence, poly-<em>o</em>-alkyl and poly-<em>o</em>-alkoxyanilines (alkyl = CH₃, C₂H₅, C₃H₇, alkoxy = OCH₃, OC₂H₅, OC₃H₇) have been synthesized. The polyaniline salt is insoluble in organic solvents but these polymers are soluble both in salt and base forms. The solubility increases with increase in the length of the side chain but conductivity decreases. The polypropyl and polypropoxyanilines have been synthesized for the first time.
