Abstract: PROBLEM TO BE SOLVED: To provide an improved method of preparing a stable dispersion of a fumed metal oxide having an especially high solids loading and a high pH.
SOLUTION: The method of preparing a dispersion of a fumed metal oxide in a liquid carrier comprises the following sequential steps: (a) providing a liquid carrier at a pH that effects dissolution of the metal oxide at a rate the same as or greater than the metal oxide dissolution rate in water at a pH of about 8; (b) mixing with the liquid carrier, in any order, one or more aliquots of both a fumed metal oxide and a metal ion source to form a dispersion, such that the dispersion does not coagulate; and (c) optionally adjusting the pH of the dispersion to the pH of the liquid carrier in the step (a). The method allows for the preparation of the dispersion to be done with a high solids loading and at a high pH. Furthermore, the dispersion can have a shelf-life of at least one hour or more at 25°C.

Abstract: Methods to predict the rheological properties of composition comprising a filler in a matrix are described. The present invention further involves determining the difference between the work of cohesion and the work of ahhesion for a filler and a matrix in order to quantitatively predict the rheological properties of the system, such as yield point. The ability to predict such properties has numerous advantages. The present invention further relates to a rheological master curve and a method to produce the curve which permits one to predict a rheological property of a composition comprising a filler in a matrix based on the particular polymer used and the particular filler used. Also disclosed is a method of method of choosing a filler to achieve a desired rheological property using the rheological master curve described herein.

Abstract: The present invention relates to a method of selecting and/or developing particulate material for a composition comprising the particulate material and a matrix by using at least one homogeneous interaction parameter alone or in combination with at least one heterogeneous interaction parameter. These parameters may comprise at least one interfacial potential property value, at least one value derived from an interfacial potential property value, at least one component of an interfacial potential property value, or combinations thereof for a particulate material and for the matrix. Process and performance maps, as well as methods for mapping, are also disclosed.

Abstract: The invention provides an aqueous dispersion comprising fumed silica particles, colloidal silica particles, and water. The fumed silica particles have a BET surface area of about 70 to about 140 m /g, and the colloidal silica particles have a BET surface area of about 110 to about 150 m /g. Also, the total amount of silica in the dispersion is about 35% to about 60% by weight, and the fumed silica particles comprise about 25% to about 80% by weight of the total amount of silica in the dispersion. The invention also provides a coating composition and a recording medium incorporating the inventive dispersion.

Die vorliegende Erfindung betrifft ferner die Bestimmung der Differenz zwischen der Kohäsionsarbeit und der Adhäsionsarbeit für einen Füllstoff und eine Matrix, um die rheologischen Eigenschaften des Systems, wie z. B. die Fließgrenze bzw. Streckgenze quantitativ vorherzusagen. Die Möglichkeit, diese Eigenschaften vorherzusagen, bietet zahlreiche Vorteile. Die vorliegende Erfindung bezieht sich ferner auf eine rheologische Master- bzw. Modellkurve und ein Verfahren zur Aufstellung der Kurve, die es ermöglicht, eine rheologische Eigenschaft einer Zusammensetzung, die einen Füllstoff in einer Matrix umfasst, vorherzusagen auf der Basis des jeweils verwendeten Polymers und des jeweils verwendeten Füllstoffs. Beschrieben wird außerdem ein Verfahren zum Auswählen eines Füllstoffs, um eine erwünschte rheologische Eigenschaft zu erzielen, unter Verwendung der rheologischen Masterkurve, wie sie hier beschrieben ist.
