    Abstract

    The authors researched means for copolymerizing various aromatic monomers with ethylene to verify improved electrical breakdown characteristics. First, the effect of the benzene rings on electrical breakdown characteristics was studied using ethylene-styrene copolymers. The polymer containing 0.22 wt percent (0.06 mol percent) styrene showed the impulse breakdown strength 25 percent greater than a low-density polyethylene. The breakdown strength decreased with a further increase in styrene content. Considering the changes in the structure and physical properties brought about in the benzene rings by the addition of styrene, we assumed a conflicting effect of the benzene ring, i.e., energy absorption characteristics, enhancing electrical breakdown strength and a negative effect caused by hindered crystallization. As the second step of the study, allylbenzene (ABz) and 4-phenyl-1-butene (PB) were each copolymerized with ethylene for the purpose of reducing crystallization blocking. Allyl styrene (AS) and 4-styryl-1-butene (SB) were each copolymerized with ethylene to improve its crosslinking characteristics. This paper reports the results of a study using these copolymers.
