摘要

用差示扫描量热法（DSC）、X光电子能谱（XPS）、小角X射线散射（SAXS）、动态力学分析（DMA）和透射电子显微镜（TEM）对低分子量不饱和聚酯（GR）增塑的EPDM磺酸锌盐（Zn-SEPDM）的形态结构进行了研究。结果表明

GR能与Zn~（2+）离子配位络合

削弱离子间的作用

从而降低了Zn-SEPDM的玻璃化温度。GR尚能诱导Zn-SEPDM基体结晶

改善Zn-SEPDM的力学性能。

Abstract

The morphology of zinc -neutralized sulfonated EPDM (Zn-SEPDM) plasticized with low molecular weight unsaturated polyester (GR) was studied through DSC

XPS

SAXS.DMA and TEM. The results show that GR can coordinate with Zn2+

weaken the interaction between ions

lower the 7g of Zn - SEPDM. Besides

GR can also induce Zn -SEPDM crystallization and improve its mechanical property.
