Polyethylene Resin
Yoshikazu HOSHIMURA*,1, Shun KOBAYASHI* and Kiyoshi KINOSHITA**(Received September 15, 2006; Accepted January 24, 2007)

We investigated the effects of the space charge distribution of low-density polyethylene by adding an antioxidant,and elucidated the possibility of producing new electric materials constructed of low-density polyethylene by adding
an antioxidant. Furthermore, we examined variations of maltese cross from both the crystal structure and theinsulation resistance measurement of the sample. We added an antioxidant to the sample in order to interrupt theoxidizing chain reaction, which is the most critical among oxidizing mechanisms of polyethylene. In this experiment,
after heat treatment of the sample is performed in addition to the addition of the antioxidant, we could confirm anaccumulating condition of space charge. From the above, it was discovered that the oxidation-resistant polyethylene,by adding an antioxidant, causes a decrease of maltese cross as well as the accumulation of positive and negative
charges within the sample.
