A composition of matter wherein the composition comprises a siliceous substrate having silanols on the surface and a polymer selected from the group consisting essentially of a water soluble polymer, a water soluble copolymer, an alcohol soluble polymer, an alcohol soluble copolymer, and combinations of such polymers, wherein the polymer is chemically bonded to the siliceous substrate by a silane linking material having the general formula O 3/2 SiQY that is derived from an alkoxy-functional silane having the general formula (RO) 3 SiQX and processes for preparing the crosslinked polymer that is chemically bonded to the surface of the siliceous substrate. |
