摘要：

The graft copolymers of N-(hydroxymethyl) acrylamide were synthesized by radical grafting of N-(hydroxymethyl) acrylamide onto the xanthan gum as a substrate. On increasing the concentration of N-(hydroxymethyl) acrylamide the grafting parameters decreased gradually, whereas the similar parameters for homopolymer increased. The antioxidant activity of the graft copolymer was 5% less than for xanthan gum and 17% less than for butylated hydroxytoluene. The hydrogen peroxide scavenging activity of graft copolymer was 31 and 15% higher than that of xanthan gum and butylated hydroxytoluene, respectively. The hydroxyl radical scavenging activity of graft copolymer was 15% less than gum and 16% more than butylated hydroxytoluene. The superoxide scavenging activity of graft copolymer was 11% less than that of xanthan gum and 24% more than that of butylated hydroxytoluene.
