| Abstract: | N-isopropylacrylamide(NIPAAm) was used to synthesize NIPPAAmhomopolymer (nonionized) and NIPAAm-sodium methacrylate copolymer(ionized). Swelling equilibria for both gels were carried out in aqueous NaCl solution with concentrations ranging from 1×10-3 to 5mol/kg H2O at 25℃.The effects of concentration of comonomer， crossliner and total monomers on gel swelling performance were also discussed. Meanwhile, the distribution of NaCl in gel-phase and coexisting liquid-phase was measured. |
