摘　　要：本文通过自制的连续光聚合设备,基于悬浮光聚合的方法制备了表面带有环氧官能团的功能化高分子微球。将甲基丙烯酸缩水甘油酯(GMA)与二乙烯基苯(DVB)共聚,制备出PGMA高分子微球,并考察了引发剂用量、单体配比、溶剂配比、搅拌速率、光照强度等对微球粒径以及形貌的影响。采用电子显微镜、红外光谱(IR)、热重(TG)等手段对样品的结构、形貌及性能进行了表征。通过优化实验条件,实现了微球粒径的可控性;用IR确定微球含有环氧基团;通过显微镜照片可以看出所制备的微球球形度较好。上述结果证实用本文方法制备的微球表面富含环氧基,易于表面改性。In this paper,the functional polymer microspheres with epoxy functional groups on the surface were prepared by using a self-made continuous photopolymerization device based on suspension photopolymerization.Polymeric PGMA microspheres were prepared by copolymerization of glycidyl methacrylate(GMA)with divinylbenzene(DVB).The effects of initiator dosage,monomer ratio,solvent ratio,stirring rate and light intensity on microsphere size and morphology were investigated.The structure,morphology and properties of the samples were characterized by electron microscopy,infrared spectroscopy(IR)and thermogravimetric(TG).By optimizing the experimental conditions,the particle size controllability of the microspheres was realized.IR determined that the microspheres contained epoxy group,and the microspheres prepared by the microscope had a good sphericity.These results showed the surface of the microscope is rich in epoxy and easy to be modified.
