淀粉接枝丙烯酰胺高吸水性树脂的制备

PREPARATION OF SUPER WATER -ABSORBENT RESIN BY GRAFTING ACRYLAMIDE ONTO CORN STARCH

以硝酸铈铵为引发剂，研究了玉米淀粉接枝丙烯酰胺制备高吸水性树脂的方法。对不同聚合条件和水解条件等因素对树脂性能的影响进行了探讨。并测定了树脂的吸水率、保水性和热稳定性，其吸水率可达４８０ｇ水／ｇ树脂。

The present paper is to investigate the preparation of super water-absorbent resin by grafting reaction of acrylamide onto corn starchy using ammonium ceric nitrate as ini- tiator. The intluences of Polymerization and hydrolysis conditions on the properties of super water - absorbent resin were studied. The properties of this super water - ab- sorbent resin such as water absorption ,water-retaining property ,thermal stability have heen also studied.
