Poly(methyl methacrylate) microcapsules were prepared by the in situ polymerization of methyl methacrylate and N,N'-methylenebisacrylamide on the surface of CaCO_3 particles, followed by the dissolution of the CaCO_3 core in ethylenediaminetetraacetic acid solution. The microcapsules were characterized using fluorescence microscopy, atomic force microscopy, scanning electron microscopy, and Fourier transform infrared spectroscopy. Similarly, the microcapsules were prepared by RAFT reagent of particles surface.

以甲基丙烯酸甲酯和N，N‘-亚甲基双丙烯酰胺为原料，在CaCO3颗粒表面进行原位聚合，然后在乙二胺四乙酸溶液中溶解，制备了聚甲基丙烯酸甲酯微胶囊。用荧光显微镜、原子力显微镜、扫描电子显微镜和傅里叶变换红外光谱对微胶囊进行了表征。同样，采用表面RAFT试剂制备微胶囊。
