Abstract

Long-chain diacrylate CROSSLINKERs based on linear a, w-diols were synthesized and characterized using FTIR and 1H NMR spectroscopy. The highest reaction yield (99.5%) was due to POLYETHYLENE GLYCOL DIACRYLATE 1000 (PEGDA-1000). Then, KAOLIN-containing poly (potassium acrylate-acrylic acid) superabsorbent composites and KAOLIN-free counterparts were synthesized using PEGDA-1000. The effect of the CROSSLINKER concentration on swelling, rheological and thermo-mechanical properties was investigated. Absorption capacity of the composite HYDROGELs (having~38% KAOLIN) was unexpectedly higher than that of KAOLIN-free HYDROGELs. This was attributed to an interfering effect of KAOLIN during the polymerization. Glass transition temperature was increased with CROSSLINKER concentration enhancement and addition of KAOLIN up to about 10oC and 28oC, respectively. Making such K-containing superabsorbents may be taken as an effective action to achieve more durable and cheaper superabsorbents for agricultural uses.
