SYNTHESIS AND CHARACTERIZATION OF SOME POLYALKYL-ANILINES AND POLYALKOXY-ANILINES

Since poly-3-alkylthiophenes are more processible than polythiophene, it is expected that poly-o-alkyl and poly o-alkoxyanilines will evince better processibility than polyaniline. Hence, poly-o-alkyl and poly- o-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. T he solubility increases with increase in the length of the side chain but conductivity decreases. The polypropyl and polypropoxyanilines hav e been synthesized for the first time.
