Abstract
A preliminary X‐ray photoelectron spectroscopic (XPS) investigation on poly[4,4′‐isopropylidenebis(1,4‐phenyleneoxyethylene) diacrylate] samples obtained by photocuring on several substrates in the presence of a fluorine containing acrylic monomer is reported. Quantitative calculations based on F~1s~/C~1s~ area ratios and C~1s~ peak fitting show a noticeable fluorine surface enrichment that ranges, depending on the substrate, from 17 wt.‐% to 59 wt.‐% of fluorine containing moiety. The calculations also reveal the presence of a concentration gradient at the surface.
