Surface cross-linking of acrylic-based water absorbent particles was conducted to enhance swollen gel strength. Partially neutralized acrylic acid was synthesized via solution polymerization, and then modification of superabsorbent polymer was imposed on the surface of its particles using bisphenol A diethylene glycidyl ether (BADGE) and 3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexane carboxylate (CAE) resins. The two-step surface treatment was conducted initially, by homogenous soaking in treatment solution containing cross-linker and solvent (90 wt% acetone and 10 wt% deionized water) and then heating at 170 °C, to complete reaction, subsequently. ATR-FTIR spectroscopy, rheometry analysis, swelling capacity measurements in deionized water and saline solution (0.9 wt% NaCl) and swelling kinetics measurments were also employed for accurate investigation. Effect of both epoxy resins content as the effective parameter has been examined. Addition of a little amount of cross-linker raised the storage modulus about 30 % but the higher amounts of the reagents increased it up to 100 %. Both resins could significantly improve the absorbency under load. Heating duration was another effective parameter which has been investigated for BADGE resin. Two different trends have been observed for variant heating intervals. Network structure has been revealed by means of average M c calculating by the modified rubber elasticity theory. Besides, swelling kinetics of BADGE-treated sample was approximated by employing Voigt-based viscoelastic model and its parameters have been derived and compared with diethylene glycol diglycidyl ether-treated sample, as well.
