Silicon dioxide which bears partially or fully silylated polysilicic acid chains on its surface

The invention relates to silicon dioxide which bears partially or fully silylated polysilicic acid chains on its surface, wherein the sum of silanol groups of the silicon dioxide surface (SiOH) and grafted-on silylating agent radicals (SiRa) is greater than the number of silanol groups on the surfac...

Zusammenfassung:	The invention relates to silicon dioxide which bears partially or fully silylated polysilicic acid chains on its surface, wherein the sum of silanol groups of the silicon dioxide surface (SiOH) and grafted-on silylating agent radicals (SiRa) is greater than the number of silanol groups on the surface of untreated silicon dioxide, where a can be 1, 2 or 3 and R can be identical or different and are each a substituted or unsubstituted hydrocarbon radical.
