| 摘 要： | 以硝酸铈铵为引发剂，在几种水－有机溶剂体系中一步合成了吸水性淀粉－丙烯腈接枝共聚物。其中所含的ＰＡＮ均聚物比水作溶剂时的多。在水－正丁醇溶液（Ｖ／Ｖ＝１∶３）中，ＰＡＮ的接枝效率为８３％，淀粉的接枝效率为７２％，产品的吸水倍数为８２０ｇ／ｇ。

| Abstract: | The starch-polyacrylonitrile grafting copolymers with water absorbility were prepared by one step synthesis in several aqueous organic solvent systems using ceric ammonium nitrate as the initiator. They contain more homopolymer PAN than those prepared in water alone. Grafting efficiencies for PAN and starch are 83% and 72% in H 2O-n BuOH, respectively. The water absorbility of the product is 820g/g. |
