Abstract
Polarization dependent XANES spectra were obtained by use of synchrotron radiation for oriented polyethylene and fluorinated polyethylenes: (1) elongated polyethylene (PE) film, (2) elongated poly(vinylidene fluoride) (PVDF) film, (3) poly(tetrafluoroethylene) (PTFE) film, (4) oriented evaporated film of hexatriacontane. CH3(CH2)34CH3 as a model compound of PE, (5) oriented evaporated film of perfluoroeicosane, CF3(CF2)18CF3 as a model compound of PTFF. Pronounced polarization dependence was observed for each compound, which allows unambiguous assignments of the XANES spectrum. Fluorination effects on the XANES spectra was also discussedKeywords
