 Abstract: Films of polyimide (>8 nm) were formed on a polycrystalline silver surface following heating of a vapor-deposited layer of 4,4,-oxydianiline (ODA) and 1,2,4,5-benzenetetracarboxylic anhydride (PMDA). The imidization reaction leading to polymer formation was followed in situ with X-ray photoelectron spectroscopy. The uncertainties inherent in a quantitative analysis of the composition of the top 8 nm of the surface layer (corresponding to the sampling depth of the technique) are discussed with respect to thick films of ODA and PMDA adsorbed on a clean Cu(lll) surface at 200 K. The fully cured polyimide film contains excess ODA-like and PMDA-like constituents as trapped molecules or terminal groups.
