Pp. Vansaarloos et al., AN X-RAY PHOTOELECTRON-SPECTROSCOPY STUDY OF POLY(METHYL METHACRYLATE) SURFACE-MODIFIED BY 193 NM LASER-RADIATION/, Polymer bulletin, 33(3), 1994, pp. 331-338
The chemistry of poly(methyl methacrylate) subjected to 193-nm radiati
on, emitted by an argon-fluorine excimer laser, was studied by X-ray p
hotoelectron spectroscopy. From the O/C atomic ratios measured at two
different sampling depths, it is concluded that the role of depolymeri
zation in the laser ablation process may be less important than previo
usly suggested.
