Abstract
Oil-polymer interactions were investigated using various combinations of polymer and oil. The current magnitudes in oil-polymer systems were in the following order: LDPE>HDPE>PP>PET>>FEP. These results are discussed, considering the solubility parameter (SP), the crystallinity of the polymer, and impurities in the polymer. It was found that the magnitude of the charging current in oil-polymer systems cannot be explained by the SP value alone. It is affected by impurities in the polymer (including antioxidant) close to the oil-polymer interface. Antioxidant is extracted from the polymer during sulfuric acid treatment. The treatment of sulfuric acid reduces the current and changes the TSC (thermally stimulated current) spectrum.<>
