ABSTRACT:
The present invention provides a polymerizable organosilicon nanocapsule, which includes:a nanoscale core A, which includes:at least one particle comprising at least one oxide or mixed oxide, KA-O, of at least one metal or semimetal selected from the group including main groups 2 to 6 of the Periodic Table, transition groups 1 to 8 of the Periodic Table, lanthanides, and mixtures thereof;andan organosilicon shell B, which includes:at least one organosilicon compound having the formula (Ia):in-line-formulae description="In-line Formulae" end="lead"?(Si′O—)xSi—R  (Ia)in-line-formulae description="In-line Formulae" end="tail"?wherein R is a vinyl or allyl group;wherein x is a number from 0 to 20;wherein remaining free valences of Si are each independently (KA-O)—, SiO— or —Z;wherein remaining free valences of Si′ are each independently (KA-O)—, SiO—, —R, or —Z;wherein the Z's are each independently hydroxyl or alkoxy radicals; andwherein each Si and Si′ in the shell B have not more than one R group attached thereto.
