Abstract:
An embodiment of a method of encapsulation of a material comprises dispersing high aspect ratio particles in a monomer and/or a polymer to form a suspension mixture, adding the suspension mixture to an aqueous mixture to form an aqueous reaction mixture, heating and mixing the aqueous reaction mixture to encourage the formation of substantially spherical-shaped beads, quenching the aqueous reaction mixture after the substantially spherical-shaped beads are formed, and collecting the substantially spherical-shaped beads.
Abstract:
A pigment contains one or more substantially spherical-shaped beads. Each substantially spherical-shaped bead includes one or more high aspect ratio particles encapsulated within an encapsulating material. Resinous compositions containing this pigment and a plastic, for example a polycarbonate, have a flowline-free colored, sparkling and/or metallescent appearance.
