摘要：
The effects of monomer concentration and feed composition in the graft copolymerization of a mixture of vinyl acetate (VAc) and methyl acrylate (MA) onto cellulose, initiated by ceric ion, are studied. Two procedures for the reactants addition were employed and several grafting parameters were measured. MA is more reactive toward grafting than VAc, and the VAc-MA mixture shows an intermediate behavior. Minor amounts of MA favor VAc grafting, and minor amounts of VAc disfavor MA grafting. VAc is oxidated more easily by ceric ion than is MA. An explanation of the results is presented. © 1990, Taylor & Francis Group, LLC. All rights reserved.
