Abstract

The space charge distribution and the impulse breakdown phenomena of acrylate-graft-polyethylenes, like acrylic acid and n-butylacrylate, were investigated. Heterocharges generated in low-density polyethylene were decreased with the introduction of acrylic acid and changed to homocharge formations with the increase of graft ratio. On the other hand, the space charge accumulation in n-butylacrylate grafted polyethylene remained unchanged for the whole range of the graft ratio. The impulse breakdown strength of the acrylate-graft-polyethylene was increased and changed according to the graft ratio
