Abstract

In the present paper the chemical modification upon exposure with UV light of 185 nm and 254 nm in an Ar atmosphere of the surface of polymethylmethacrylate (PMMA) is studied with time‐of‐flight secondary ion mass spectrometry (TOF‐SIMS). The results show that UV photodegradation of PMMA does not induce large changes in the TOF‐SIMS spectra. However, changes in the relative peak intensities for the photolysed samples and comparison with results from PMMA fragmentation upon ion bombardment show that the photodegradation has proceeded to a considerable extent. In addition, small peaks are observed due to ions that originate from oxidized PMMA groups.
