ORGANOSILYL FUNCTIONALIZED PARTICLES AND THE PRODUCTION THEREOF

摘要

Particles of metal and non-metal oxides may be readily functionalized with organosilyl groups, even in the absence of catalysts, when methylene-spaced alkoxysilanes are used for functionalizing. When an excess of alkoxy groups relative to metal-OH groups are present, the resulting functionalized particles exhibit high reactivity, particularly upon exposure to moisture. Functionalization is particularly useful with particles of organopolysiloxane resins.
