In some cases, grafting is used to form the copolymers. Examples of chains combined with PDMS in this way include polyfethylene oxide) fluorinated chains, alkyl acrylates and alkyl methacrylates, polyfvinyl alcohol), polyfether sulfones), and polyurethanes. Grafting has also been used to introduce t-butylamine and t-butylammonium biocidal functionalities, and to improve the adhesion of silicone rubber to polyurethane. In other cases, the siloxane groups are simply placed on the ends of chains, such as onto some polybenzoxazines. ... 

Polysulfones are materials of great technological interest due to their applications as polymeric membranes, resists for microelectronics, heat-resistant materials in aerospace applications, matrices for composites, etc. It has been shown that ion beam treatment applied in the low-keV range is a suitable way to modify some relevant properties of polysulfones, such as solubility or electrical conductivity (117, 118], XPS is probably the most suitable analytical method for the characterization of ion-beam-induced changes in the composition and chemical state of polysulfone,s, e.g of aromatic polyfether sulfone) (PEiS) [119, 120).
