A functionalized ethylene-based polymer dissolved in an appropriate solvent and applied to a nonpolar surface can change the surface polarity/characteristics of the nonpolar surface. This change to the surface polarity/characteristics of the nonpolar surface allows adhesion of materials, such as paint, to surfaces such as polypropylene, polyethylene and polyolefin elastomers.
