The incorporation of commodity polyolefins into high performance materials is currently limited by their chemical and physical properties. The present invention is a synthetic platform for introducing a diverse range of chemical functionalities into commercial polyolefins. This post-polymerization functionalization features site-selective C–H xanthylation of the polyolefin which allows for further synthetic diversification of the polymer backbone via a single intermediate. This synthetic platform provides facile entry to functionalized polyolefins that could unlock new properties of the parent materials for their application in high-performance applications such as composites, coatings, and adhesives.
