Abstract :
The space charge accumulation in highly polar polyolefins compared with polyethylene homopolymer have been evaluated with the pressure wave propagation technique. It was found that homocharges dominate in the copolymers while mainly heterocharges are present in LDPE homopolymer. The difference between degassed peroxide crosslinked compounds based either on EBA or LDPE or a blend of the two was less. Heterocharges were typically the main feature in all these samples
