gamma-ray irradiated beads of poly(styrene-divinylbenzene) (PS-DVB) have been graft copolymerized with polyacrylic acid. Preirradiated PS-DVB beads were refluxed with acrylic acid in water, benzene, or toluene. Percentage of grafting was studied under various reaction parameters like total dose, reaction time, and molar concentration. Effects of reaction media, temperature of reaction, and presence of Mohr salt on the percentage of grafting were also studied. From the swelling property of PS-DVB beads in DMF and dichloromethane, it appeared that no appreciable cross-linking had occurred in the process of grafting. (C) 1996 John Wiley & Sons, Inc.
