Abstract
A process, a composition, and an article of manufacture are disclosed. The process includes generating a cyclic monoterpene derivative. The generating includes oxidizing a cyclic monoterpene to generate a ketone derivative and oxidizing the ketone derivative to form a lactone derivative. The composition and the article of manufacture include a polymer having monomer repeat units derived from a lactone derivative of a cyclic monoterpene.
