本文用自行研制的催化剂合成了一种新型线型低密度聚乙烯，测试了其电性能。结果表明，与常规高压低密度聚乙烯和线性低密度聚乙烯相比，该聚乙烯具有更高的体积电阻率、更高的击穿强度和更少的间隔层电荷积累。我们还测试了新型聚乙烯和常规低密度聚乙烯共混物的电性能，发现低密度聚乙烯含量高达90wt%的共混物与新聚乙烯的值几乎相同。用透射电子显微镜对共混物的形态进行了观察，发现共混物保持了低密度聚乙烯含量的90wt%以上的特性。讨论了形态与电性能的关系，并与传统低密度聚乙烯进行了比较。
In this paper electrical properties of a novel linear low-density polyethylene synthesized with a catalyst, developed by our unique technique, were measured. It was found that this polyethylene had a higher volume resistivity, a higher breakdown strength and less spacer charge accumulation than conventional high-pressure low-density polyethylene and linear low-density polyethylene. We also measured electrical properties of blends of the new polyethylene and the conventional low-density polyethylene and found that the blends which contained up to 90 wt% of the low-density polyethylene had nearly the same value as the new polyethylene. The morphologies of the polyethylene were observed by using transmission electron microscope (TEM) and found that the blends kept the characteristics shown in the new polyethylene up to 90 wt% of the low-density polyethylene content. The relationship between morphology and electrical properties is discussed and comparison is made between the new polyethylene with those of the conventional low-density polyethylenes.
