Grafting onto cellulose. IV. Effect of complexing agents on fenton's reagent (Fe²⁺H₂O₂)‐initiated grafting of poly(vinyl acetate)

Adsorption study of copper (II) by chemically modified orange peel

“…In addition, the presence of the initiator in the reaction mixture also leads to polymerization of MA, producing homopolymer. A similar mechanism has been reported by other authors [27,28]. Scheme 1 shows the proposed grafting Scheme 1.…”

Modification of carbohydrate polymers via grafting of methacrylonitrile onto pregelled starch using potassium monopersulfate/Fe2+ redox pair

“…The reduction in grafting parameters after 0.004 mol l −1 PMPS may be explained by self‐termination of growing grafted chains because of abundance of free radical species, and the presence of excess of Fe 3+ ions causing termination of grafted chains. These ions have been reported to be ideal retarders of free radical polymerization 15–17…”

“…The enhancement in grafting may be due to the increase in KHSO 5 /Fe 2+ concentration adduct which undergoes decomposition at the pregelled starch surface resulting in the generation of a number of free radical species at a faster rate than that at which addition of monomer takes place. The decrease in grafting may be attributed to the excess of Fe 3+ ions produced during disproportionation of the KHSO 5 /Fe 2+ couple that retards the radical polymerization reaction 15–17…”

Graft Copolymerization of Methyl Acrylamide onto Jute Fibers Initiated by Peroxydisulfate Catalyzed by Fe(III)

“…That has been reported by Rogovin et af. 39 and Mishra et al 40 (iv) Effect of Temperature The effect of temperature on percent grafting is shown in Figure 1. It has been observed that the percent grafting increases upto 50°C and then decreases.…”
