Novel crosslinked polymeric substrates methods of preparation and end use applications of the substrates

摘要

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 O3/2SiQY that is derived from an alkoxy-functional silane having the general formula (RO)3SiQX and processes for preparing the crosslinked polymer that is chemically bonded to the surface of the siliceous substrate.
