通过运用介电分析的方法对聚氯乙烯和含叔胺聚ε－己内酯聚氨酯共混物进行了研究。介电研究表明，当聚酯聚氨酯的含量在５０％（质量）左右时，介电损耗曲线表现出单一的玻璃化转变，低于或高于此比例，体系在现出部分相容的两相结构，归一化的介电损耗曲线表明，共混物的损耗曲线宽度宽于聚氨酯和聚氯乙烯的损耗曲线宽度，理论计算表明，体系的相互作用参数Ｘ＿（１２）为０．００４。
Through the use of dielectric analysis of polyvinyl chloride and tertiary polyepsilon caprolactone polyurethane blends were studied. Dielectric studies have shown that the dielectric loss curve exhibits a single glass transition at or below about 50% by mass of the polyester polyurethane, with the system exhibiting a partially compatible two phase The structure and normalized dielectric loss curves show that the width of the loss curve of the blends is wider than that of polyurethane and PVC. Theoretical calculations show that the interaction parameter X 12 is 0.004.
