Sliding of Poly(Vinyl Chloride) on Metals Studied by Auger Electron Spectroscopy.
Abstract
The sliding of poly(vinyl chloride) on nickel, iron, and S-Monel has been studied by Auger Electron Spectroscopy. Polymer was not transferred to the metals, rather, shear appeared to take place at the interface. The metal was progressively chlorinated as the polymer made multiple passes on the surface. The thickness of this chlorine film was the order of one atomic layer. Electron-induced desorption studies indicate that the chlorine is chemisorbed to the metal. These results are interpreted as evidence for mechanically induced and/or thermal degradation of the polymer during sliding. Degradation products of HCl and Cl2 which chemisorb to the metal are evolved near the interface.
