淀粉接枝三元共聚物的合成及其吸水缓释性能的研究

目的:合成一种能够缓慢的释放其吸存的水溶液中有效成分的功能胶囊,延长水溶液中有效成分的释放时间.方法:通过反相悬浮聚合合成吸水树脂,将其吸收水溶液凝胶化后再用固体粉末包裹.结果:这种方式能够有效地延长水溶液中有效成分的释放时间.结论:该胶囊可减少一次性施尿素造成的尿素挥发损失;可以吸收生物钾酶水溶液,有利于植物的成长;还可以吸收不同功能的非离子溶液,如药液、ABT生根粉水溶液,提高其利用率.

Synthesis of starch-grafted tripolymer and its property of retardative releasing effective components

Objective:To synthesize a functional gelatin having the properties of retardative releasing some effective components from its absorbed previously aqueous solution of the effective components. Method: A water-absorbing resin composed of starch grafted ternary copolymer of AM-AA-AANa grafted onto starch was synthesized by using inverse suspension polymerization.Result:The releasing time of effective components was prolonged in water solution.Conclusion: Using the retardative releasing gelatin capsule can solve the problems of a decrease in its use efficiency.The capsule can also absorb potassium enzyme solution and help plants grow;and can absorb different non-ionic solution,such as drug solution and ABT solution,and enhance their use efficiency.
