Abstract: The present invention is an article of construction formed from an article adhesively-bonded to a layering material through (a) reactive coupling of a functionalized nitroxide or (b) the adhesion of components in a polymer matrix made from or containing a polymer, an organic peroxide, and a functionalized nitroxide. The initial article may be expanded. It may also be polar or nonpolar. Similarly, the layering material may be polar or nonpolar. Other embodiments of the present invention are described, including other articles and methods for preparing the articles.
