【摘要】 本文用逆相乳液聚合方法合成了一种新型药物载体淀粉微球。其过程为水溶性的单体接枝到淀粉上,同时接技共聚物的支链间发生交联反应,生成不溶于水的微球。 借助于扫锚电镜,粒度分布测试仪,压汞仪可以容易地将这些淀粉微球进行粒度分级和分类,测得总孔体积为1.3001～0.8344ml/g。总孔面积为50.900～31.280m~2/g,此外还测得微球直径约为40μm。这些微球可以根据要求携带不同种类的电荷,因而利用吸附的方法,淀粉微球可以用做药物载体。更多还原

【Abstract】 This new carrier of drug starch microspheres was prepared by inveres emulsion polymerization system. The water soluble monomer was grafted onto starch in the meantime the branched chains of these graft copolymers were crosslinked to form water insolnble microspheresIt has been shown that the starch microspheres is-40μm in diameter, besides the site of particle are well-distributed and classificated easily, the total intrusion volume is 1.3001-0.8344ml/g, and the total pore area is 50.900-31.280m2/g by observation and measurment of scanning electron microscopy, particle diameter distributmeter Penetrometer. As it is required this microspheres can be carried different electric charge. So the starch microspheres may be carried drug easily by adsorbability.更多还原
