3-Ethyl-6-vinyltetrahydro-2H-pyran-2-one (EVP) is a CO₂-derived lactone synthesized via Pd-catalyzed telomerization of butadiene. As EVP is 28.9% by weight CO₂, it has received significant recent attention as an intermediary for the synthesis of high CO₂-content polymers. This article provides an overview of strategies for the polymerization of EVP to a wide variety of polymer structures, ranging from radical polymerizations to ring-opening polymerizations, that each take unique advantage of the highly functionalized lactone.
