Abstract
An adhesive may be formulated with a functional component that reacts in the presence of ultraviolet light with a neighboring functional component to form a nonreversible bond therebetween. The functional component may include at least one —C═C— functional group that is able to undergo dimerization with a neighboring component. A method for making the adhesive includes covalently bonding the functional component to a support polymer, wherein the functional component may be covalently bonded to the support polymer by a linking molecule. A kit containing the adhesive and an ultraviolet light source is also provided.
