The instant invention relates to cationic alkoxyamines, which are useful as polymerization initiators/regulators in a controlled stable free radical polymerization process to produce intercalated and/or exfoliated nanoparticles from natural or synthetic clays. The invention also relates to improved nanocomposites produced by this process and to the use of these nanocomposite compositions as, for example, coatings, sealants, caulks, adhesives and as plastic additives.

A method for producing a high-quality barium titanyl salt includes using, as the fluids to be treated, at least two kinds of fluids, namely, a barium titanium mixed solution that is obtained by dissolving both a barium compound and a titanium compound in a solvent, a compound solution that is obtained by dissolving, in a solvent, a compound capable of deposing the barium and titanium contained in the barium-titanium mixed solution into a barium titanyl salt, and if necessary, one or more other fluids; and mixing these fluids together in a thin film fluid formed at least between two treating surfaces and to form a barium titanyl salt. The treating surfaces are so arranged as to face each other in an approachable/separable state with one of the treating surfaces and being capable of turning relatively to the other.
