The homogeneous grafting of hydrophilic monomer onto cellulose derivatives was carried out in an aqueous system at 30, 50, 70 and 90 °C during reaction periods of 30 to 180 min. The graft polymer was isolated by ethanol from the reaction mixture, dried, and weigh. The grafted polymer was characterized by IR spectroscopy as well as microscopic sample morphology detected by electron scanning microscopy. The water absorption capacities and grafting values of grafted cellulose derivatives were also determined. The maximum grafting yield was obtained at 30 °C. Copyright © 2002 John Wiley & Sons, Ltd.
