Abstract

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.
