Abstract
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.
