To examine the influence of acetophenone on the space charge evolution in polyethylene (PE), additive-free LDPE and LLDPE sheets were studied. The first one is a two-layered specimen consisting of a non-treated sheet and an acetophenone-soaked sheet, while the other is an LDPE or LLDPE sheet, onto which a few drops of acetophenone were split so that the sample surface was coated with acetophenone. Positive charges were easy to migrate from the acetophenone-existing region to the non-existing region in the case of LDPE, while negative charges were difficult. Further it was found that both positive and negative charges are rather immobile in LLDPE, and they tend to accumulate at the interface between the acetophenone-existing and non-existing regions.
