离聚体的结构表征——Ⅴ.含氟离聚体中离子微区稳定性的研究

摘要: 本文用DSC方法研究了羟酸型含氟离聚体中不同金属离子种类、可离子化基团含量、配位结构单元构型及离子微区大小对离聚体中离子微区稳定性的影响。实验表明:离聚体中金属离子配位能力愈强,羟酸含量愈高,离子微区尺寸愈大,则相应离聚体中离子微区稳定性愈大。铅高聚体>锌离聚体>钙离聚体>钠离聚体。

Abstract: Due to the formation of coordination structure units and their aggregation, the ionic domains in ionomer restrict macrmolecular chain motion, so it is feasibel that the stability of ionic domain in the ionomer was discribed by the determination of heat ef
