摘要：

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 H-1-NMR, C-13-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 200degreesC. 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. (C) 2003 Wiley Periodicals, Inc.
