摘　　要：利用FTIR和漫反射 傅里叶变换红外 (DR FTIR)方法对醋酸乙烯酯 (VAc) 二乙烯苯 (DVB)共聚物微球表面功能化反应进行了研究。结果表明 ,DR FTIR光谱比透射FTIR光谱能够获得更多的微球表面信息。A series of vinyl acetate (VAc)-divinylbenzene (DVB) copolymeric microspheres were prepared by suspension copolymerization. The surface hydroxyl group onto the VAc-DVA copolymeric microspheres ran be obtained by saponifiction reaction on their surface. By reaction between the reactive chorine group of a dye and the hydroxyl groups on the VAc-DVB copolymeric microspheres, cibacron blue F3G-A, as an affinity ligand, was covalently immobilized on the surface of the VAc-DVB copolymeric microspheres. The characterization of surface functionalizationed VAc-DVB copolymeric microspheres was studied by means of FTIR and diffuse reflectance FTIR spectroscopy. The results indicate that DR-FTIR spectra give out more detailed information of the modified microspheres' surface than FTIR spectra does.
