Miscibility of conductive blends of poly(o-anisidine) with poly(2-alkyl-2-oxazoline)s. Journal of Applied Polymer Science 65 (2) : 391-397. ScholarBank@NUS Repository.00218995https://scholarbank.nus.edu.sg/handle/10635/94263HCl-doped poly(o-anisidine) (PANIS-HCl) and undoped poly(o-anisidine) (PANIS-base) were blended with poly(2-methyl-2-oxazoline) (PMOx) or poly(2-ethyl-2-oxazoline) (PEOx) by solution casting from dimethyl sulfoxide. Blends containing 50 wt % or less of PANIS-HCl or PANIS-base were flexible and homogeneous. The glass transition temperature of the blend continuously shifted away from that of PMOx or PEOx with increasing PANIS-HCl or PANIS-base content, indicating miscibility. The shift in the Tg value was larger for the PMOx blend than for the corresponding PEOx blend, suggesting a stronger interpolymer interaction in the former blend. Fourier transform infrared spectroscopic studies indicated the presence of specific interactions in the blends as evidenced by the changes of C=O and NH bands. Blends containing 50 wt % of PANIS-HCl showed conductivity of about 10-4 S/cm. © 1997 John Wiley & Sons, Inc.ArticleNOT_IN_WOS
