ABSTRACT:
Surface-modified solids bearing groups of the formula Iin-line-formulae description="In-line Formulae" end="lead"?SiR12—R—NH2 (I),in-line-formulae description="In-line Formulae" end="tail"?are prepared by reacting a solid having OH groups on a surface thereof with a cyclic silazane of the general formula IIwhereR is a divalent optionally substituted hydrocarbon radical optionally containing heteroatom containing groups, andR1is a hydrogen atom, or a monovalent optionally substituted hydrocarbon or hydrocarbonoxy group optionally containing heteroatom-containing groups. The surface-modified solids are preferably metal oxide particles. Such surface-modified particles are useful in numerous products.
