“…Residual monomers of graft copolymers were analyzed by a reverse phase Shim‐Pack C18 (ODS) column (Shimadzu, Japan, 15 cm × 4.6 mm i.d.) in a Shimadzu HPLC system consisting of an LC 6A pump equipped with UV‐Vis spectrophotometric detector, according to the procedure of Saroja et al,28 which involves separation using 0.05 M KH 2 PO 4 , pH 5.5 at 1 mL min −1 at 30°C. A 10 mL volume of standard acrylonitrile, diluted in glass distilled water, was injected onto the column and detected at 220 nm.…”

The polysaccharide, kappa carrageenan (kC), was modified using ceric-initiated graft copolymerization of acrylonitrile (AN) under inert atmosphere in a homogeneous aqueous medium. Grafting was confirmed using FTIR spectroscopy, solubility test, elemental analysis, acid hydrolysis, and thermogravimetric analysis (TGA). kC-graft-poly(AN) products had a higher thermal stability than kC as revealed by TGA analysis. The polyacrylonitrile branches were isolated by acidic degradation of the carrageenan main chains and characterized by size exclusion chromatography (SEC). Residual monomers were not found by HPLC in graft copolymers stored even for longer periods. The effect of various factors affecting on grafting, i.e., concentration of the initiator, monomer, and polysaccharide as well as the reaction time and temperature were studied by conventional methods to achieve the optimum grafting parameters. The graft copolymerization reactions were kinetically investigated using semiempirical expressions and a suitable rate expression has been derived. According to the empirical rates of the polymerization and the graft copolymerization of AN onto kC backbone, the overall activation energy of the graft copolymerization reaction was estimated to be 20.96 kJ/mol.
