Acrylic copolymers that include the controlled placement of functional groups within the polymer structure are provided. The copolymers contain a reactive segment and a non-reactive segment and are manufactured via a controlled radical polymerization process. The copolymers are useful in the manufacture of adhesives and elastomers.

Acrylic polymers having controlled placement of functional groups

Modification of functional groups along a polymer backbone to render the groups activatable upon exposure to actinic radiation is described. The polymers are typically controlled architecture polymers. Also described are adhesives containing the modified architectured polymers and related methods of use.

Post-polymerization functionalization of pendant functional groups

Methods for forming melt processable, actinic radiation polymerizable and crosslinkable adhesives are described. In certain versions, the adhesives or pre-adhesive compositions include two initiators and are polymerized and/or crosslinked by exposure to actinic radiation such as UV light or electron beam radiation. Also described are pre-adhesive compositions including polymerizable monomers, articles including the adhesives, and various methods and systems related to the adhesives and their application. In addition, various apparatuses are described for polymerizing or crosslinking the compositions.

Two stage methods for processing adhesives and related compositions

Acrylic copolymers that include the controlled placement of particular functional groups within the polymer structure are provided. The copolymers contain at least two reactive segments and are manufactured via a controlled radical polymerization process. The copolymers are useful in the manufacture of adhesives and elastomers.

Controlled architecture polymers

Acrylic copolymers that include the controlled placement of particular functional groups within the polymer structure are provided. The copolymers comprise a first reactive segment of including a functional group selected from the group consisting of a UV active functional group, a reactive functional group, a non-reactive functional group, and combinations thereof and a second segment including a functional group selected from the group consisting of a reactive functional group, a non-reactive functional group, and combinations thereof. The acrylic copolymers are manufactured via a controlled radical polymerization process. The copolymers are useful in the manufacture of adhesives and elastomers.

Controlled architecture polymerization with photoinitiator groups in backbone

Polymers having ordered architectures and one or more reactive functional groups incorporated in select blocks or regions of the polymer in particular proportions relative to other regions in the polymer, are described. The polymers are well suited for use in adhesive compositions, and particularly for pressure sensitive adhesive compositions. In addition, various methods for forming the noted polymers and adhesive compositions utilizing the ordered polymers are disclosed.

Ordered architectures in acrylic polymers

Acrylic block copolymers are described which are inherently tacky. Also described are compositions of the copolymers which exhibit properties enabling their use as pressure sensitive adhesives, without addition of tackifiers and/or subsequent processing.
