| Abstract: | Thermoswelling sensitive water-absorbent resins(TSAR) were synthesized by solution polymerization of acrylamide,acrylic acid and thermo-responsive macromonomer.The structure was characterized by IR.The water-absorbent properties of TSAR were investigated at different temperature in pure water and 0.9% NaCl brine,respectively.The results showed that TSAR exhibited thermoswelling properties in pure water and 0.9% NaCl brine. |
