Abstract

Organosilicon nano/microhybrid systems or microhybrid systems having nanoscale and/or microscale oxide particles (KA—O), and an organosilicon shell with at least one organosilicon constituent of the general formula Ia wherein the organosilicon constituent of the shell B is attached to the oxide particles via one or more covalent linkages of formula Ib A process for preparing a composition comprising organosilicon nano/microhybrid systems or microhybrid systems directly in a synthetic resin composition allows in situ preparation of a curable resin. The compositions may be used as coating materials for producing scratch resistant and abrasion resistant coatings.
