The present disclosure relates to acrylic adhesive emulsions comprising a core-shell polymeric component comprising an inner core and an outer shell containing at least one pendent functional group; a polyfunctional component capable of reacting with at least one of the pendent functional groups on the outer shell; wherein the inner core is free of functional groups reactive with the pendent functional groups on the outer shell; and wherein the pH of the emulsion is 6.5 or less; and wherein the emulsion is a fast-setting, one part, aqueous, adhesive. Bonded articles made therefrom, and methods of bonding articles using these emulsions are also disclosed.

One part, fast-setting, aqueous adhesive emulsions

Microencapsulated delivery vehicles comprising an active agent are disclosed. The microencapsulated delivery vehicles may be introduced into products such that, upon activation, the product provides a functional benefit to a substrate, such as a user's skin.

Microencapsulated delivery vehicle having an aqueous core

Microencapsulated delivery vehicles comprising an active agent are disclosed. In one embodiment, the microencapsulated delivery vehicles are heat delivery vehicles capable of generating heat upon activation. The microencapsulated heat delivery vehicles may be introduced into wet wipes such that, upon activation, the wet wipe solution is warmed resulting in a warm sensation on a user's skin. Any number of other active ingredients, such as cooling agents and biocides, can also be incorporated into a microencapsulated delivery vehicle.

A composition of matter includes a polymerizable mixture comprising 1 to 99 weight percent of a first monomer and an initiator therefor, the first monomer being one of 1) at least one free-radically polymerizable monomer or 2) at least one cyanate ester monomer, and 99 to 1 weight percent of a second monomer and an initiator therefor, the second monomer being the member of 1) or 2) that is not selected as the first monomer, wherein the curative for the cyanate ester is a transition metal-containing organometallic compound curing agent and the curative for the free-radically polymerizable monomer is a free-radical generating curing agent or a transition metal-containing organometallic compound. The polymeric mixtures are useful, for example, in applications requiring high performance, such as high temperature performance; in composites, particularly structural composites; structural adhesives; vibration damping materials; electronic applications such as printed wiring boards, semiconductor encapsulants and electronic adhesives; photoresists; injection molding and prepregs; protective coatings; tough self-supporting films; and high performance binders. In addition, a curable composition including (1) an ethylenically unsaturated monomer or (2) an ethylenically unsaturated monomer and a cyanate ester monomer, and certain organometallic neutral compounds is useful in the graphic arts.

Acrylate-only and epoxy-acrylate thermoset resins exhibit high temperature damping behavior. These materials are suitable for damping vibrations in structures and component parts of devices where high temperature performance is required, such as in automobiles, aircraft, industrial equipment and appliances.
