A water-soluble polymeric UV-absorber with polyvinylamine as backbone and benzotriazole type UV absorber as anti-UV functional group was synthesized by grafting brominated(2'-acetoxy-5'-methylphenyl)-2H-benzotriaz...A water-soluble polymeric UV-absorber with polyvinylamine as backbone and benzotriazole type UV absorber as anti-UV functional group was synthesized by grafting brominated(2'-acetoxy-5'-methylphenyl)-2H-benzotriazole onto polyvinylamine. The intermediates and synthesized polymeric UV absorber were characterized by ~1H NMR,MS,IR and UV spectroscopy.The finishing properties of the polymeric UV absorber on cotton were investigated to show good UV protection property and wash fastness.展开更多
