Claim Text:
1. Method for the preparation of a particulate, polybranched organic/inorganic hybrid polymer by a sol-gel process, said hybrid polymer having form of an inorganic core carrying organic branches, wherein the method comprises at least the following two steps in chronological sequence: A) the core is prepared by controlled hydrolysis and condensation of a silane with a structure: in which X=NR 1 R 2 , wherein R 1 , R 2 are chosen among hydrogen, saturated or unsaturated C 1 -C 18 -alkyl, substituted or not substituted aryl, wherein the carbon chains of said silane optionally can include one or more of the elements oxygen, nitrogen, sulphur, phosphorus, silicon and boron, and optionally may include one or more hydrolyzable silane units, or R 1 , R 2 are chosen among condensation products, addition products of one or more type of chemical substances selected from the group consisting of acids, alcohols, phenols, amines, aldehydes or epoxides, B is a linkage group chosen among saturated and unsaturated C 1 -C 18 -alkylene, substituted or non-substituted arylene in which the carbon chains of said substances optionally may include one or more branching and optionally one or more of the elements oxygen, nitrogen, sulphur, phosphorous, silicon and boron, Y is chosen among hydrolyzable residues selected from the group consisting of alkoxy, carboxyl, and halogen, B) the organic branches are developed by:
