Graft Copolymerization of butyl acrylate onto sodium salt of partially Carboxymethylated Psyllium by Photopolymerization

The graft copolymerization of butyl acrylate onto sodium salt of partially carboxymethylated psyllium (Na-PCMPsy) in an aqueous medium was investigated, using ceric ammonium nitrate (CAN) as a photo initiator. The reaction variables including concentration of initiator, nitric acid, monomer and amount of the backbone as well as time and temperature have been varied for establishing grafting. The influence of these reactions conditions on the grafting yield has been discussed. Fourier transforms infrared spectra analysis and scanning electron microscopy characterized the graft copolymer
