Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . A process, comprising: generating a cyclic monoterpene derivative, the generating comprising: oxidizing a cyclic monoterpene to generate a ketone derivative; and oxidizing the ketone derivative to form a lactone derivative. 2 . The process of claim 1 , further comprising polymerizing the cyclic monoterpene derivative. 3 . The process of claim 2 , wherein the polymerizing comprises reacting the lactone derivative to form a polyester. 4 . The process of claim 2 , wherein: the generating further comprises epoxidizing the lactone derivative; and the polymerizing comprises reacting the epoxidized lactone derivative to form a polycarbonate. 5 . The process of claim 1 , wherein the cyclic monoterpene is an endocyclic alkene. 6 . The process of claim 5 , wherein the oxidizing the cyclic monoterpene comprises reacting the cyclic monoterpene with potassium permanganate (KMnO 4 ). 7 . The process of claim 1 , wherein the cyclic monoterpene is an exocyclic alkene. 8 . The process of claim 7 , wherein the oxidizing the cyclic monoterpene comprises reacting the cyclic monoterpene with selenium dioxide (SeO 2 ). 9 . A composition, comprising: a polymer comprising monomer repeat units derived from a lactone derivative of a cyclic monoterpene, the lactone derivative generated in a process comprising: oxidizing a cyclic monoterpene to generate a ketone derivative; and oxidizing the ketone derivative to form the lactone derivative. 10 . The composition of claim 9 , wherein a plurality of the monomer repeat units comprise at least one sidechain functional group. 11 . The composition of claim 9 , wherein each of the monomer repeat units has two reactive sites. 12 . The composition of claim 9 , wherein the polymer is a polycarbonate or a polyester. 13 . The composition of claim 9 , wherein the cyclic monoterpene is an endocyclic alkene. 14 . The composition of claim 13 , wherein the oxidizing the cyclic monoterpene comprises reacting the cyclic monoterpene with potassium permanganate (KMnO 4 ). 15 . The composition of claim 9 , wherein the cyclic monoterpene is an exocyclic alkene. 16 . The composition of claim 15 , wherein the oxidizing the cyclic monoterpene comprises reacting the cyclic monoterpene with selenium dioxide (SeO 2 ). 17 . An article of manufacture, comprising: a polymer comprising monomer repeat units derived from a lactone derivative of a cyclic monoterpene, the lactone derivative generated in a process comprising: oxidizing a cyclic monoterpene to generate a ketone derivative; and oxidizing the ketone derivative to form the lactone derivative. 18 . The article of manufacture of claim 17 , wherein a plurality of the monomer repeat units comprise at least one sidechain functional group. 19 . The article of manufacture of claim 17 , wherein a plurality of the monomer repeat units comprise at least one sidechain functional group. 20 . The article of manufacture of claim 17 , wherein each of the monomer repeat units has two reactive sites.
