| 摘 要： | 以纤维素和羧甲基纤维素作为载体,将带有羧基的2,4-二氯苯氧乙酸和带有羟基的五氯酚等农药分别与它们相结合。制备了分子链上键合有农药的高聚物。进而通过水解试验其释放农药的性能。结果表明:农药在纤维素链上的替代度可以通过控制反应条件加以调节,所制备的键合有农药的高聚物可以自行水解而缓慢地释放出农药,并随水解时间的延长,释放速度逐渐减慢。

| Abstract: | Macromolecules, a pesticides-macromolecules combination, have been prepared. The pesticides bearing carboxyl or hydroxyl group are bonded to the carriers, such as cellulose and carboxymethyl cellulose (CMC), but it will set itself free from the main chain of the macromolecular carriers by hydrolysis. The substituted degree of pesticides on the corriers, cauld be adjusted by varying the controlling conditions.The high polymer so prepared will release pesticides free spontaneously but slowly by immersing in water, and the release rate will proceed slower and slower as the time flows. |
