Methods for preparing silicone-containing polymers by essentially adiabatic polymerization methods are disclosed. The polymerization system includes free radically polymerizable monomers. The monomers include ethylenically unsaturated silicone-containing monomers and/or mercapto-functional silicones as well as additional free radically polymerizable monomers. The silicone-containing polymers are useful as adhesives or release materials.

Bulk polymerization of silicone-containing copolymers

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

Reinforced articles particularly adapted for use in combination with an adhesive to form reinforced adhesive tape articles that are stretchable as well as hand-tearable along with being highly conformable and cinchable.

Stretchable, hand-tearable, conformable, and cinchable reinforced adhesive tape articles

Described herein are release layers formed via solventless extrusion. The release layers include a polyolefin and an alkyl dimethicone. The release layers exhibit tailorable release properties from pressure-sensitive adhesives. The release layers are simple to make and require no post-treatment in order to impart the observed release properties. The release layers are adaptable to multilayer extrusion, blown film formation, and cast film formation techniques.

Release films via solventless extrusion processes

The present application is directed to adhesive articles and release liners. Namely, the present application is directed to an article comprising an adhesive layer with a structured surface. The structured surface comprises a first groove and a second groove recessed into the adhesive layer from a reference plane defined by the adhesive surface on either rim of the groove. In some embodiments, the second groove is contained within the first groove, and in other embodiments the grooves are separate. The first groove and the second groove have walls. The wall angle of the first groove with respect to the reference plane is non-zero and is smaller than the wall angle of the second groove with respect to the reference plane. The application is also directed to release liners for the adhesive article, wherein the surface of the release liner is the inverse of the adhesive surface.

Adhesive articles and release liners

A vinyl graphic marking film or label coated with a pressure sensitive acrylic adhesive designed to achieve high or permanent adhesion to polymeric low energy surfaces is disclosed. In addition to good adhesion to low energy surfaces, the graphic marking film or label may have microperforated or micro-rough edges which initiate tearing when removal is attempted. The article maintains flexibility and film strength for easy fabrication in graphic marking film or label manufacture.

Pressure sensitive adhesives for use on low energy surfaces

Adhesives useful in applying articles, such as tapes, labels, signs, decals, emblems, car moldings, protective or optical films, etc., to surfaces to which articles normally do not adhere well, such as surfaces containing fluorine and polycarbonate, for example. The adhesives include a copolymer of one or more monoethylenically unsaturated alkyl (meth)acrylate monomers, one or more monoethylenically unsaturated secondary or tertiary amide-functional monomers, and optionally one or more acidic monomers.
