摘要:
An aqueous dispersion comprising particles of a layered host material and functional-active organic compound dispersed in an aqueous medium, wherein the weight ratio of layered host material to functional-active compound is less than 20 and at least 50% of the functional-active organic compound in the dispersion is intercalated between layers of the layered host material particles, and further wherein the aqueous medium comprises additional soluble salts or ionized molecules or polymers distinct from the functional-active compound and has an ionic strength of greater than 5 mS/cm. A method of delivering a desired functional-active organic compound to a target system, comprising delivering such an aqueous dispersion to the target system, wherein the aqueous dispersion comprises the desired functional-active organic compound intercalated in a layered host material, and additional soluble salts or ionized molecules or polymers which are distinct from the functional-active compound and which are also present in the target system to which the functional-active compound is delivered.

摘要:
The present invention relates to polymeric composites comprising inorganic fillers and organic, or organometallic, polymers. The filler compositions are used in the preparation of inorganic-organic polymeric composites, and, in particular, light curable composites. The composite fillers are used in dental applications, such as tooth restorations, for example, cavity fillings, adhesive compositions, veneers, crowns, bridges and teeth replacements. The inventive composition is a composite filler comprising porous inorganic particles having a diameter of 2-25 microns and a polymer occupying the pores of the porous inorganic particles, wherein the composite filler has a diameter of 2-25 microns.
