Patent ID: 8137590

Claim:
A composition of matter comprising solid functionalized particles which contain at least one structural element of the formulae [1] to [3], —NR 2 + —B-A − [1], ═NR + —B-A − [2], ≡N + —B-A − [3], and/or a protonated or deprotonated form thereof, wherein the structural elements of the formulae [1] to [3] are covalently bound to the particles by reacting (P) particles having an average primary particle size diameter less than 10 μm with silanes or siloxanes containing a structural element of the formula [1] to [3], and wherein A is a sulfonate radical —SO 3 , a carboxylate radical —C(O)O or a phosphonate radical —P(O)(OR 7 )O, B is (CR 1 2 ) m , a substituted or unsubstituted alkyl radical interrupted by heteroatoms, or a substituted or unsubstituted aryl or heteroaryl radical, R and R 7 are each hydrogen or a substituted or unsubstituted hydrocarbon radical, R 1 is hydrogen, a halogen or a substituted or unsubstituted hydrocarbon radical, and m is 1, 2, 3, 4 or 5, with the proviso that the nitrogen atom in the formula [2] is an endocyclic nitrogen atom of an aliphatic heterocycle, and with the proviso that the nitrogen atom in the formula [3] is an endocyclic nitrogen atom of an aromatic heterocycle.
