Abstract: C-1s and O-1s of the 3,5-bitrifluoromethylated poly(aryl ether) terminated with phenylethynyl moieties(2CF3-PAE-PEP) before/after crosslinking were tested by the X-ray photoeletron spectroscopy(XPS). The measurements show that some of the CO bonds in the molecule structure will be broken if the films are crosslinked in the air, which is able to form some new CO bonds with the oxygen in the air. However, the ratios of the groups in the films cured in nitrogen remain the same as that of the uncured samples. It is the the forth harmonic of the stretching vibration of CO bond(4ν<sup>φ<sub>C=O) that causes the absorption loss at the wavelength 1 382 nm.

Key words: Fluorinated poly(aryl ether), Crosslinking, Absorption loss, XPS spectrum
