More Book Details

Description of the Book:

A new water soluble polyelectrolyte has been synthesized by the alkyl sulfonation of the aramid poly-(p-phenyleneterephthalamide) (PTTA) to form poly(p-phenyleneterephthalamide propanesulfonate) (PPTA-PS). This polyelectrolyte is soluble in water to greater than 18% by weight when the poly- aramid is alkyl sulfonated to 66%. Characterization and structural analysis of the polyelectrolyte was facilitated by a Carbon 13 Nuclear Magnetic Resonance study of the model compound benzanilide and its alkyl and alkyl sulfonate derivatives, as well as of an alkyl derivative of PPTA. The preparation of a molecular level composite of polypyrrole and PPTA-PS has been pursued by electrochemical polymerization of pyrrole using PPTA-PS as both the electrolyte and the polymeric dopant ion. The composite materials exhibit conductivities of 1 ohm/cm and improved thermal stabilities when compared to poly(pyrrole tosylate). (KT
