明胶-丙烯酸-丙烯酰胺可降解高吸水树脂的制备

Preparation of biodegradable gelatin-g-poly(acrylic acid-co-acrylamide) superabsorbent

研究了溶液聚合法制备明胶-丙烯酸(AA)-丙烯酰胺(AM)接枝共聚可降解高吸水性树脂的方法,测试了不同条件下得到的产品的吸(盐)水性能,并优选出合适的合成条件。合成的高吸水性树脂的吸水倍率可达865 g/g,吸盐水倍率达91 g/g。

Poly（ acylic acid-co-acrylamide） grafted gelatin with high water absorbency and biodegradability is synthesized. The suitable conditions of synthesis are chosen after testing the water-absorbing performance of products getton from various conditions.The obtained product has a water absorbency of 865g/g and 0.9% NaCl solution of 91 g/g.
