Derivatization with trifluoroacetic anhydride (TFAA) followed by X-ray photoelectron spectroscopy (X.p.s.) analysis is a useful method for estimating the surface concentration of hydroxyl groups in polymeric materials. High-resolution X.p.s. analysis of TFAA-derivatized poly(vinyl alcohol) and plasma-polymerized poly(allyl alcohol) reveals significant chemical shifts in the carbon atoms attached to the -OC(O)CF3 group and carbon atoms in the/3 position relative to this group.
