Abstract
Silica has been treated in a slurry with several chloromethylsilanes a nd SiCl4. After treatment, the surfaces were characterized by XPS, DRI FT and Si-27-MAS NMR. The following reactivity scale was determined: T MCS > DCDMS > MTCS > TCS. XPS was found to be a very useful technique to complement NMR and vibrational spectroscopies, mainly from a quanti tative point of view.
