Abstract: 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.

Abstract: Crosslinkable compositions, crosslinked compositions, articles containing these compositions, and methods of making the articles are provided. The crosslinkable compositions, which include two (meth)acrylate copolymers plus a tackifier, are used to form the crosslinked compositions upon exposure to ultraviolet radiation. The crosslinked compositions can function as pressure-sensitive adhesives. The crosslinkable compositions are well suited for use with hot melt processing methods.

Abstract: A crosslinkable composition, a crosslinked composition formed upon exposure of the crosslinkable composition to ultraviolet radiation or ionizing radiation, articles containing these compositions, and methods of making the articles are described. The crosslinkable compositions contain two different (meth)acrylate copolymers and can be applied to a substrate using an extrusion process. While being extruded, the crosslinkable compositions advantageously are resistant to crosslinking and/or increased molecular weights. The crosslinked compositions can function as adhesive compositions that are particularly well suited for use in electronic devices.

Abstract: Crosslinkable compositions, crosslinked compositions, articles containing these compositions, and methods of making the articles are provided. The crosslinkable compositions, which include two (meth)acrylate polymers, are used to form the crosslinked compositions upon exposure to ultraviolet radiation. The crosslinkable and crosslinked compositions are free or substantially free of tackifiers. The crosslinked compositions can function as pressure-sensitive adhesives. The crosslinkable compositions are well suited for use with hot melt processing methods.

Abstract: A method for preparing an acrylate adhesive is provided by the steps of partially polymerizing a monomer mixture to provide a syrup polymer composition having a high molecular weight solute copolymer. This first syrup composition is again polymerized to provide a second syrup polymer composition having a low molecular weight copolymer. The second syrup polymer composition is provided with a crosslinking agent and further polymerized to provide the adhesive composition.
