Crosslinked poly(glycidyl methacrylate) has been functionalized by ethanolamine and subsequently by xanthation. The xanthate based beads were used for anchoring Fe 2 + ions, after which they have been used in conjunction with H202 as a redox catalyst system for aqueous polymerization of acrylamide. The polymer beads were characterized for percentage modification at subsequent stages by elemental analysis, Fourier-transform infra-red spectroscopy and pore size distribution. The efficiencies of polymerization with the polymer-supported catalyst and with a conventional system were compared with respect to the yield and molecular weight.
