Abstract

Polyaniline (PANI) is a semi-rigid polymer which does not melt and has only limited solubility. Protonation to yield electrical conductivity generally renders a polyelectrolyte which is still less processible. Even selection of the dopant to be bulky or “functionalized” does not render PANI-complex to become melt-processible unless additional additives are used. Neste Oy (Finland) in cooperation with Uniax (U.S.A.) has identified several proprietary additives to allow melt-processibility. We show that in this way PANI-complex starts rheologically to behave in many respects like a conventional polymer. For example, in blends of PANI-complex with polypropylene, their viscosity ratio can be used to render either the PANI-complex or PP continuous, completely analogically to the “classical” polymer blends.
