摘　　要：通过乳液聚合方法制备以丙烯酸丁酯、苯乙烯为主要单体的胶乳互穿网络聚合物(LIPN)。以合成宽温域、高阻尼性能的材料为目的,通过改变单体溶胀时间、交联剂用量来研究它们对材料阻尼性能的影响。主要采用动态力学分析方法(DMA)对材料的阻尼性能进行测试,同时还考察了各组成聚合物的附着力。A series of LIPN polymer of styrene （St）, butyl acrylate （BA） monomers were obtained by means of emulsion polymerization method. This paper was aimed to prepare broad damping temper ature rang and high tang vibration damping materials. The influence of soakage, the content of crosslinking agent in the core or in the shell on the damping property was studied. Dynamic mechanical analysis （DMA） was used to test the damping properties of materials,at the same time the strength of conglutination was investigated.
