AbstractTwo polymerizable room temperature ionic liquids (RTIL), AMPS-BA and AMPS-DMAEMA, were synthesized by neutralization of 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS) with butylamine (BA) and 2-(N,N-dimethylamino)ethyl methacrylate (DMAEMA), respectively, in acetone, followed by evaporation of the solvent under a reduced pressure at room temperature. The RTILs were characterized by differential scanning calorimetry to determine their glass transition temperatures (Tg). Co-polymeric gels of the RTILs with 2-hydroxyethylmethacrylate (HEMA) were prepared by aqueous solution polymerization using N,N′-methylenebisacrylamide (MBAm) as a cross-linker and ammonium persulfate as an initiator. The superabsorbency of the gels in water and various organic solvents was gravimetrically investigated. The results showed that the Tg of AMPS-BA and AMPS-DMAEMA was -47.7°C and -45.8°C, respectively. Poly(AMPS-BA-co-HEMA) gels exhibited superabsorbency in both water and various organic solvents, while poly(AMPS-DMAEMA-co-HEMA) gels did not swell in any liquids. The mechanism for the swelling difference between poly(AMPS-BA-co-HEMA) gels and poly(AMPS-DMAEMA-co-HEMA) gels was critically discussed.
