Free‐radical copolymerizations of 1‐vinyl‐2‐pyrrolidone with 2‐acrylamido‐2‐methyl propane sulfonic acid at different feed ratios were investigated. The copolymers were characterized by 1 H‐NMR, 13 C‐NMR, and FTIR. The copolymer composition was determined from the elemental analysis. The molecular weights ( M w , M n ) and dispersities of the copolymers were determined by gel permeation chromatography. Thermogravimetric analysis indicated that copolymers are stable at least up to 200°C. Temperature dependency of the alternating current (ac) conductivities was investigated by means of impedance spectroscopy. The direct current (dc) conductivities of the samples were obtained from the ac conductivity data. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 90: 3347–3353, 2003
