Abstract: The present invention relates to a super-absorbent polymer having excellent properties, both centrifugal retention capacity (CRC) and absorption under pressure (AUP) having been improved by introducing a surface crosslinked layer crosslinked by surface-modified inorganic particles, and to a method for preparing the same. The super-absorbent polymer comprises: a base resin powder containing a crosslinked polymer of water-soluble ethylene-based unsaturated monomers having an at least partially neutralized acidic group; and a surface crosslinked layer formed on the base resin powder, wherein inorganic particles may be chemically bound to the crosslinked polymer contained in the surface crosslinked layer, via an oxygen-containing bond or a nitrogen-containing bond.

Abstract: A particulate material for chromatographic use comprising silica particles is provided having a skeleton structure containing silsesquioxane cage moieties. The material is useful as a chromatographic material, for example in HPLC. The silica particles may be hybrid organo-silica particles wherein the silsesquioxane moieties comprise a cage structure having silicon atoms positioned at corners of the cage wherein one or more silicon atoms positioned at the corners of the cage carry an organic group. A preferred method of preparing the particulate material comprises hydrolysing a silsesquioxane as a co-component of a hydrolysis mixture, especially in a Stöber or modified Stöber process.
