Abstract
PURPOSE: The titled composition that is made by adding an aromatic dinitrodiene to an electrically insulating polymer, thus being suitably used to cover power cables, because of its good processability and high water-tree resistance.
CONSTITUTION: An electrically insulating polymer, preferably low-density polyethylene, (100pts.wt.) is kneaded with an aromatic dinitrodiene having a basic structure of formula I or II, such as 2,2'-dipyridine or 1,10-phenanthrolin (0.005W 5pts.) under heating. A crosslinked or partially crosslinked polyolefin also is used as the polymer. The resultant composition is molded into any form of insulation layers and used for joint parts and auxiliary ones in the cables as well.
