高聚物的性能取决于结构。本文以两种苯乙烯-乙烯-丁烯-苯乙烯嵌段共聚物(SEBS)为研究对象,通过红外、核磁、差示扫描量热法和动态力学分析对其结构进行了剖析,并对其制备的大输液膜制品的形貌和性能进行了表征。结果表明,SEBS中硬段含量、软段成分及不饱和度都会对其制品性能产生影响。
The performance of a polymer depends on the structure. In this paper, the two kinds of styrene-ethylene-butylene-styrene block copolymer (SEBS) as the research object, its structure was analyzed by infrared, nuclear magnetic, differential scanning calorimetry and dynamic mechanical analysis, and its The morphologies and properties of the prepared infusion films were characterized. The results show that hard segment content, soft segment composition and unsaturation in SEBS all affect the properties of the product.
