    Abstract: A method of making a filled resin includes providing functionalized particles; and combining and homogenously mixing the functionalized particles with an organic matrix in a vacuum kneader to provide the filled resin so that the functionalized particles comprise at least about 20% by weight of the filled resin. The step of providing functionalized particles can also include providing a feedstock of (i) untreated particles, (ii) a surface treatment agent reactive with the particles, and (iii) solvent, and directing the feedstock through a continuous reactor maintained at a temperature sufficient to react the particles with the surface treatment agent to provide the functionalized particles in less than about 4 hours; and directing the functionalized particles from the continuous reactor directly into the vacuum kneader. In another aspect, the a finished resin comprises at least about 20% by weight of functionalized particles in an organic matrix

    Abstract: The present invention includes ultraviolet curable compositions preferably containing discrete, crystalline zirconia nanoparticles with reactive, or copolymerizable, surface modification, in a polymerizable monomer/oligomer resin mixture. It is believed that copolymerizable surface modification provides a functional group that enables the functionalized particle to co-polmerize with the reactive monomers, oligomers, and crosslinkers in the formulation. Relative to surface modifation of the nanoparticles, acrylate functionality is preferred over methacrylate functionality. On the other hand, methacrylate functionality is preferred over non-reactive, or nonpolymerizable, functionality. As the nanocomposite cures, the resultant network is heavily crosslinked by selection of raw materials with substantial acrylate functionality.
