摘　　要：聚合物材料制备过程和聚合物中添加剂的含量及分布决定了材料的性能,拉曼光谱技术为相关研究提供了一种有效的表征手段。基于拉曼光谱的基本原理,介绍了表面增强拉曼光谱、拉曼光谱成像、激光显微共聚焦拉曼光谱等多种拉曼光谱衍生技术,总结了相关技术在聚合物加工和聚合反应过程中的应用,评述了聚合物中添加剂分布的检测,涵盖了乳化剂、染料以及其他添加剂的浓度、分布及迁移规律等,并对拉曼光谱衍生技术进行了展望。Polymer preparation processes and additive concentration/distribution determine the properties of a polymer material.Raman spectroscopy is a powerful technique for this characterization.The fundamental of Raman spectroscopy,advanced techniques derived from conventional Raman spectroscopy,such as surface enhanced Raman spectroscopy,Raman spectroscopic imaging and laser microscopic confocal Raman spectroscopy are presented,and their applications for polymer processing and polymerization are summarized.Properties of polymer additives(emulsifiers,dyes and other additives)including concentration,distribution and migration studied using various Raman techniques are also reviewed.In addition,the outlook for the development of Raman spectroscopy techniques is also discussed.
