Abstract
Poly(vinyltrimethylsilane) (PVTMS), poly(dimethylsiloxane) (PDMSO), po ly(methylsilsesquioxane) (PMeSSO), and poly(phenylsilsesquioxane) (PPh SSO) were bombarded by 2.5 keV Ar+ ions and the beam induced chemical effects were: studied by XPS and XAES, For PVTMS the gradual developme nt of a new component on the high kinetic energy side of thr. original Si KL(23)L(23) peak was observed, which was attributed to the formati on of [SiC4] units present in a densely crosslinked matrix, For the po ly(organosiloxanes) PDMSO, PMeSSO and PPhSSO a kind of disproportionat ion of Si was inferred from the evolution of their Si 2p and Si KL(23) L(23) peaks, involving the transformation of a part of the original [S iCxOy] units to [SiC4]-type and [SiO4]-type ones surrounded by a dense ly crosslinked organosilicon matrix.
