Silicone-organic nanocapsules

Polymerizable organosilicon nano-capsules (IA) consist of: (A) a nano-core containing main group II-VI, sub-group I-VIII and/or lanthanide metal(loid) (mixed) oxide(s); and (B) an organosilicon shell containing organosilicon constituent(s) (II), optionally (partly) bound to A by covalent bonds.

Beschreibung
Zusammenfassung:	Polymerizable organosilicon nano-capsules (IA) consist of: (A) a nano-core containing main group II-VI, sub-group I-VIII and/or lanthanide metal(loid) (mixed) oxide(s); and (B) an organosilicon shell containing organosilicon constituent(s) (II), optionally (partly) bound to A by covalent bonds. Polymerizable organosilicon nano-capsules (IA) consist of: (A) a nano-core containing main group II-VI, sub-group I-VIII and/or lanthanide metal and/or metalloid oxide(s) and/or mixed oxide(s) (KA-O); and (B) an organosilicon shell containing organosilicon constituent(s) of formula (Si'O-)xSi-R (IIA) and/or is bound to the core A (KA-O) by covalent bonds of formula (KA-O-((Si'O)xSi-R) (IIB), such that, in both cases, the free valencies of Si are satisfied by SiO- and/or -Z, the free valencies of Si' are satisfied by SiO-, -R and/or -Z and the core B has a maximum of one R group per Si or Si' group. R = linear, branched or cyclic 1-50C alkyl; x = 0-20; and Z = OH and/or alkoxy. Independent claims are also included for: (1) organosilicon nano-capsules (IB) obtained by reacting KA-O with alkyl-trialkoxysilane(s) (with (m)ethoxy or n- or iso-propoxy groups) and optionally monomeric and/or oligomeric silicic esters and/or organofunctional siloxane(s) in situ in a liquid, curable synthetic resin or precursor; (2) the production of organosilicon nano-capsules (I) in situ in a liquid, curable synthetic resin or precursor; (3) compositions based on curable synthetic resins obtained by this process and containing the nano-capsules; (4) scratch-proof coatings obtained from the compositions; and (5) articles with the scratch-proof coating obtained.
