Abstract: The miscibility of polyaniline (PANI) salts, doped with p-phenol sulfonic acid (PSA) or 5-sulfosalicylic acid (SSA), with poly(2-ethyl-2-oxazoline) (PEOx) was studied by differential scanning calorimetry (d.s.c.) and Fourier-transform infra-red spectroscopy (FTi.r.). D.s.c. measurements show a single glass transition temperature (Tg) for each of the blends containing 5-60 wt% of PANI. The Ts value shifts away from that of PEOx with increasing PANI content. FT i. r. studies show the presence of specific interactions between the polymers. The interaction in the PEOx/PANI-SSA system is stronger than that in the PEOx/PANI-PSA system. Electrical conductivities of the blends, determined by four-point probe, range from 10-5 to 10-3 S cm-1. © 1997 Elsevier Science Ltd. All rights reserved.
