C08K 3/36

US Classification:

524284, 524492, 524493, 523220

Abstract:

A silica-based particulate material that may contain less than 5 wt. % of a multivalent cation and a method of preparing such a silica-based particulate material. The silica-based particulate material may be characterized as having a median particle size of at least 20 μm, a BET surface area of at least 90 m/g, and a pH of at least 9. 5; or as having a median particle size of up to 20 μm and a pH of at least 10. The silica-based particulate material may be used to make hydrophobic silica-based particulates, which may be characterized as having a pH of at least 10. 5.

US Classification:

25218728, 25218727, 25218625, 422 37

Abstract:

Describes a composition comprising a mixture of (1) a major amount of calcium hypochlorite, e. g. , hydrated calcium hypochlorite, and (2) a minor amount of calcium hypochlorite-compatible hydrophobic additive (other than discrete particulate Group IIA or IIIA metal stearates) in amounts sufficient to provide the composition with reduced hydrophilic properties. The composition has a solution rate in water at standard conditions that is less than the calcium hypochlorite used to prepare the composition, but sufficient for the intended application. Describes also calcium hypochlorite compositions in which the hydrophobic additive is an organo-silicon material, or a metal oxide, e. g. , amorphous precipitated silica, treated with a hydrophobizing agent, such as an organo-silicon material, e. g. , an organo-silane and/or organo-siloxane material.

Abstract:

Provided is a multi-phase particulate having a dispersed phase component dispersed in and bound to a bulk phase component. The dispersed phase component includes a metal, a metal oxide, an organometallic compound, salts thereof, and/or mixtures thereof, and the bulk phase component includes an inorganic material different from the dispersed phase component. The dispersed phase component is present in an amount ranging from 0.5 to 60 percent by weight based on total combined weight of the dispersed phase component and the bulk phase component. Related methods, compositions and composites also are provided.

Abstract:

Provided is a method of preparing a multi-phase particulate. The method includes: (1) blending together (a) a dispersed phase component of a metal, a metal oxide, an organometallic compound, salts thereof, and/or mixtures thereof, and (b) a bulk phase component of an inorganic material different from the dispersed phase component to form an admixture; and (2) dry-milling and/or compressing the admixture for a time and at a pressure sufficient to disperse the dispersed phase component in and bind the dispersed phase component to the bulk phase component, thereby forming a multi-phase particulate. Coating compositions including the multi-phase particulate also are provided.
