Conductivity of polyethylene - role of antioxidant and crosslinking by-products

The influences of crosslinking by-products and antioxidant on the electrical properties of LDPE were studied. Our approach has shown that according to the chemical processes related to antioxidant or crosslinking, the specific volume where traps are located is differentially distributed. This situation involves a modification of the distance site separation and allows to interpret the volume conductivity more especially in the high field region.
