【Abstract】 Using Fe 2+ -(NH 4) 2S 2O 8 initiation system, the modified starch retannage was synthesized by graft copolymerization of oxidizing degradation starch with acrylic acid(AA) and acrylonitrile(AN). The effect of the starch and monomer ratio, initiator concentration on the percentage of graft, the graft efficiency, the monomer conversion were investigated. The structure of graft copolymer was characterized by FTIR. The application test was carried out on goat leather.更多还原
