英文摘要	A fast swelling sulfonic acid macroporous superabsorbent composite is prepared by copolymerization of partially neutralized acrylic acid, 2-acryloylamino-2-methyl-1-propanesulfonic acid, and attapulgite. The effects of pH values, ions, and their concentration on swelling behavior of sample are investigated. The results show that the swelling behavior of sample is affected by pH value. The supercase diffusion is observed in all NaCl solutions with different pH value. An overshooting effect appears in all solutions containing multivalent cations. This phenomenon may be attributed to the reorganization of the gel structure due to the formation of complex compound between cation and polymer network. A quantitative kinetics model proposed by Diez-Pena is used to interprete it and the theoretical curves are in good agreement with the experimental data. For anions, it shows little effect on swelling process, and supercase diffusion is also observed no matter which kind of anion exists in swelling medium. POLYM. ENG. SCI., 55:681-687, 2015.
