Some amino acids and drugs imprinted spheres ( mipm ) were prepared via seeds swelling and suspension polymerization , suspension polymerization and emulsion polymerization . the physical and chemical properties of the polymers were analyzed by scanning electron microscope , thermogravimetric analyzer , electron spectrum and solid phase extraction ( microextraction ) technology . the imprinting and recognizing principle of mipm in water was studied through bi - templates imprinting method as well 分别采用种子溶胀悬浮聚合法、悬浮聚合法和乳液聚合法，在水相中体系制备得到了一系列氨基酸和药物印迹的分子印迹聚合物微球（ mipm ） ；采用扫描电镜、热失重分析、电子能谱分析、固相（微）萃取等技术对制备所得的mipm进行了分析和表征；采用双模板印迹的方法对水相中mipm的印迹和识别机理进行了探讨。
In addition , we also explored that : montmorillonite which has been treated by bs - 12 was treated secondly using mma by the method of emulsion reaction and prepared pvc / montmorillonite composite on the way of melt interaction again . by measuring xrd and mechanical properties and observing the section morphology of flexural sample through sem , we found that : after secondly treated , the intension and toughness of pvc / montmorillonite composite were greatly increased . the results indicated that using using montmorillonite can toughen and reinforce pvc effectively , so the study and application of it have a bright prospect 此外，还探讨了对经bs - 12初次处理过的蒙脱土，用甲基丙烯酸甲酯采用乳液聚合的方法进行二次处理，再次通过熔融法制成pvc蒙脱土插层复合材料，并通过x ?射线衍射测定和力学性能测试以及扫描电镜观察材料的断面形貌，结果发现，蒙脱土经甲基丙烯酸甲酯通过乳液聚合法二次处理后制成的复合材料与只用bs - 12初次处理的蒙脱土制成的复合材料相比，其强度和韧性得到了明显改善。
