以全亲水接枝共聚物PPEGMEA-g-PMAA为载体材料，以甲氨喋呤(MTX)为模型药物，通过物理包埋和化学键合法制备MTX药物缓释体系，探讨了pH值、制备方法等对载药量、包埋率和释药行为等的影响，两种体系均可以通过改变pH值来控制药物的释放和释放速率。

关键词: 全亲水接枝共聚物, 药物控释, 甲氨喋呤

Methotrexate-loaded polymeric micelles using PPEGMEA-g-PMAA double hydrophilic graft copolymer as carrier were prepared by physical entrapping and chemical bonding. The effects of pH and preparation method on drug loading content (DLC), drug loading efficiency (DLE) and drug release were studied. Drug release of both micelles can be controlled by pH.

Key words: double hydrophilic graft copolymer, drug release, methotrexate
