Abstract

In this study, a water adsorbent was synthesized by radiation grafting of acrylic acid and multifunctional monomers such as 1,2-propanediol dimethacrylate (PDMA) and 1,1,1-trimethylolethane triacrylate (TMETA) onto cellulose and its subsequent treatment with 5% NaOH. Its absorbency on $H_2O$ and 0.9 % NaCl aqueous solution was examined. The highest absorbency on water and on 0.9% NaCl aqueous solution was obtained from the addition of 0.75 vol % PDDMA and of 1.0 vol % TMETA onto acrylic acid solution, respectively. The absorbency of commercial hygienic band on water and NaCl aqueous solution was 21 g/g and 22 g/g, respectively. However, that for acrylic acid-grafted cellulose including TMETA was 298 g/g and 54 g/g, respectively.
