Sodium carboxymethyl cellulose was graft
copolymerized with sulfonic acid and sulfonate functionalized
monomers
(2-acrylamido-2-methyl-1-propanesulfonic acid [AMPS] and sodium
4-vinylbenzene sulfonate [SVBS]) in aqueous medium persulfate as an
initiator. Grafting parameters such as percentage of grafting,
grafting efficiency, conversion, and yield of SA-g-AMPS and SA-g-SVBS
were investigated gravimetrically as a function of time, monomer
concentration, temperature, and initiator concentration. The
synthesized graft copolymers were characterized by Fourier transform
infra-red, differential scanning colorimetry, and X-Ray diffraction |
