Patent ID: 8043701

Claim:
A composition comprising a curable synthetic resin and a polymerizable organosilicon nanocapsule, wherein the composition is prepared by a process which comprises: heating a precursor of the curable synthetic resin comprising a monomeric tetraacrylate, adding water and a catalyst, and optionally, a wetting agent, adding at least one organosilicon component selected from the group consisting of 3-methacryloyloxypropyltrimethoxysilane, 3-methacryloyloxypropyltriethoxysilane, 3-methacryloyloxypropylmethyldimethoxysilane, 3-methacryloyloxypropylmethyldiethoxysilane, 3-methacryloyloxy-2-methylpropyltrimethoxysilane, 3-methacryloyloxy-2-methylpropyltriethoxysilane, vinylalkoxysilanes and alkyltrialkoxysilanes, and optionally, a monomeric and/or oligomeric silicic ester which carries at least one selected from the group consisting of methoxy, ethoxy, n-propoxy, i-propoxy group and combinations thereof and has an average degree of oligomerization of from 1 to 50, and optionally, an organofunctional siloxane whose functionalities are identical or different and in which each silicon atom in the siloxane carries at least one functionality selected from the group consisting of alkyl, fluoroalkyl, cyanoalkyl, isocyanoalkyl, alkenyl, aminoalkyl, diaminoalkyl, triaminoalkyl, alkoxyalkyl, hydroxyalkyl, acylalkyl, glycidyloxyalkyl, acryloyloxyalkyl, methacryloyloxyalkyl, mercaptoalkyl, ureidoalkyl, aryl, alkoxy, methoxy, ethoxy, and combinations thereof, and remaining free valences of the silicon atoms in the siloxane are satisfied by methoxy or ethoxy or hydroxyl groups, mixing and then adding at least one oxide and/or mixed oxide (KA-0) particle of at least one metal or semimetal selected from the group consisting of main groups 2 to 6, of the Periodic Table of the Elements, transition groups 1 to 8 of the Periodic Table of the Elements, lanthanides, and mixtures thereof with thorough mixing, and removing alcohol formed by hydrolysis and/or condensation; and wherein the mole ratio of water to the at least one organosilicon component ranges from 0.5 to 3.
