中文摘要: 首先采用悬浮聚合法，制备了甲基丙烯酸缩水甘油酯(GMA)和甲基丙烯酸甲酯(MMA)的交联聚合物微球(GMA/MMA)，然后经过几步大分子反应在微球表面合成与固载了N-羟基邻苯二甲酰亚胺(NHPI)，形成固载有NHPI的功能微球GMA/MMA-NHPI。采用红外光谱(FT-IR)及扫描电子显微镜(SEM)等方法对功能微球进行了表征。结果表明，以含环氧基团的GMA/MMA为载体，通过大分子反应可实现NHPI的合成与固载。GMA/MMA-NHPI与醋酸钴（Co(OAc)2）构成的共催化体系，在分子氧对环己烷和环己醇的氧化过程中，显示出良好的催化活性。

Abstract:Crosslinked polymer microspheres of glycidyl methacrylate (GMA) and methyl methacrylate (MMA) were first prepared by suspension polymerization, obtaining the polymer microspheres GMA/MMA. Subsequently, N-hydroxyphthalimide (NHPI) was synthesized and immobilized on GMA/MMA microspheres, and the functionalized microspheres GMA/MMA NHPI were obtained through several polymer reaction steps. GMA/MMA-NHPI microspheres were characterized by infrared spectroscopy (FT-IR) and scanning electron microscope (SEM). Results show that the synthesis and immobilization of NHPI on GMA/MMA microspheres can be carried out smoothly. The compositional catalyst system of GMA/MMA-NHPI microspheres and Co(OAc)2 displays fine catalytic activity in the oxidation reactions of cyclohexane and cyclohexanol with molecular oxygen as oxygen source.
