Cellulose grafted with acrylic acid(AAc) was prepared by radiation grafting technique. The effects of reaction temperature. reaction time, monomer concentration, and the crosslinkers on the AAc grafting reaction on cellulose were examined. The amount of AAc grafted on the cellulose reached maximum at the concentration of 0.75vol% difunctional crosslinker and 1.0vol% trifunctional crosslinker, respectively. In the presence of acid, the amount of AAc grafted on the cellulose was decreased when reaction solution contains difunctional crosslinker, while that was increased when reaction solution contains trifunctional crosslinker. In the grafting reaction of cellulose with AAc and TMETA, mixture containing ferrous sulfate and acid enhanced further AAc grafting yield than mixture containing ferrous sulfate only.
