Grafting onto wool. IV. Effect of amines upon ceric ion‐initiated grafting of poly(methyl acrylate)

Grafting of poly(methyl acrylate) onto wool has been carried out in an aqueous medium at 45 ± 1°C by using ceric ammonium nitrate (CAN) in the presence of triethylamine, diethylamine, n ‐butylamine, triethanolamine, and N , N ‐dimethylaniline. The percentage of grafting varied with the nature and concentrations of the amines. Reactivity of the different amines toward grafting reactions followed the order: triethylamine > diethylamine > n ‐butylamine > triethanolamine ≥ N , N ‐dimethylaniline. In the presence of N , N ‐dimethylaniline grafting did not occur. An attempt has been made to explain the observed reactivity of Ce 4+ in various amine systems in graft copolymerization reactions.
