The present invention relates to a double-sided adhesive tape used for applications including the attachment of front glass for mobile devices. A core layer of the double-sided adhesive tape is prepared by adding an acrylic elastomer free of carbon-carbon double bonds while being highly miscible with an acrylic resin to an acrylic monomer(s) and performing curing, and thus can improve the impact resistance of the final double-sided adhesive tape. Also, the core layer may take a form of foam due to the introduced filler such as glass bubbles or organic microspheres, and thus can further contribute to improving the impact resistance of the final double-sided adhesive tape.

Acrylic rubber foam and double-sided adhesive tape comprising same

There is provided a pressure sensitive adhesive foam comprising a foam comprising a non-syntactic foam blend of styrenic block copolymer and acrylic copolymer wherein the pressure-sensitive adhesive foam has an elongation of greater than 600%, wherein the non-syntactic foam blend is a hot melt formed foam. There is also provided multilayer pressure sensitive adhesive foams, pressure sensitive adhesive foam tapes and articles made using such pressure sensitive adhesive foam.

Pressure sensitive adhesive foams and articles therefrom

The methods of preparing hot melt processable pressure sensitive adhesives include combining an elastomeric (meth)acrylate random copolymer and a discontinuous fibrous material in a hot melt mixing apparatus, and mixing to form a hot melt processable pressure sensitive adhesive. The elastomeric (meth)acrylate random copolymer may be contained within a thermoplastic pouch, and the hot melt mixture may include a relatively high level of tackifying resin. The elastomeric (meth)acrylate random copolymer may contain branching agents and photosensitive crosslinking agents. The hot melt processable pressure sensitive adhesives can be used to prepare transfer tapes.

Hot melt processable pressure sensitive adhesives containing fibrous materials

A method of making a pressure-sensitive hot melt adhesive. The method includes extruding a melt composition that includes a polymer, wherein the polymer has acidic groups covalently attached thereto, and a metal salt hydrate, wherein the metal salt hydrate has a melting point that is less than the maximum processing temperature.

Method of making a hot melt pressure-sensitive adhesive

This disclosure provides (meth)acryloyl pressure-sensitive adhesive foams and foam articles having one or more of the following properties: small cells, uniform cell sizes, pressure sensitive adhesive compositions, compliance to irregular substrates and vibration damping, and shock absorbing properties.

(Meth)acryloyl pressure-sensitive foam adhesives

A crosslinkable, pre-adhesive composition is described comprising an acid-functional (meth)acrylate copolymer and an aziridine crosslinking agent, which when crosslinked provides a pressure-sensitive adhesive and pressure-sensitive adhesive articles.
