Abstract

The effect of ceric ion and nitric acid concentrations on the graft copolymerization of a mixture of vinyl acetate and methyl acrylate onto cellulose was studied. Two procedures for the reactants addition were employed. Several grafting parameters were determined. Both ceric ion and nitric acid concentrations have a strong effect on the graft copolymerization and they affect similarly some of the polymerization parameters. A variety in the nature of the graft copolymers obtained has been reached. The general behavior of reaction parameters is discussed.
