Abstract
Official abstract text for this publication.
An article of manufacture. The article of manufacture includes a ring-opened lactide copolymer. The ring-opened lactide copolymer is formed in a process that includes reacting a functionalized lactide monomer with a BPA-derived monomer. The reaction forms a lactide copolymer, which is reacted to form the ring-opened lactide copolymer.
First claim
Opening claim text (preview).
What is claimed is: 1. An article of manufacture, comprising a ring-opened lactide copolymer formed from an epoxide-functionalized lactide monomer and a bisphenol monomer. 2. The article of manufacture of claim 1 , wherein the ring-opened lactide copolymer has the following structure: 3. The article of manufacture of claim 1 , wherein the ring-opened lactide copolymer has the following structure: 4. The article of manufacture of claim 1 , wherein the ring-opened lactide copolymer is a component of a resin. 5. The article of manufacture of claim 4 , wherein the resin is a thermoset epoxy resin. 6. The article of manufacture of claim 1 , wherein the article of manufacture is selected from the group consisting of: a coating, an electrical insulator, a fiber-reinforced plastic, and an adhesive. 7. The article of manufacture of claim 1 , wherein the ring-opened lactide copolymer is cross-linked by crosslinking moieties. 8. The article of manufacture of claim 7 , wherein the crosslinking moieties are selected from the group consisting of epoxies, isocyanates, carbonates, esters, and combinations thereof. 9. The article of manufacture of claim 1 , wherein the ring-opened lactide copolymer is formed in a process that includes a reaction to form a lactide copolymer. 10. The article of manufacture of claim 1 , wherein the functionalized lactide monomer is selected from the group consisting of: 11. The article of manufacture of claim 1 , wherein the ring-opened lactide copolymer is formed in a process that includes a ring-opening reaction with a lactide copolymer. 12. The article of manufacture of claim 11 , wherein the ring-opening reaction includes mixing the lactide copolymer with a tin(II) octanoate material. 13. The article of manufacture of claim 1 , wherein the epoxide-functionalized lactide monomer is formed in a reaction involving dimethylidene lactide. 14. The article of manufacture of claim 13 , wherein the reaction includes reacting the dimethylidene lactide with 2-oxiranemethanethiol. 15. The article of manufacture of claim 7 , wherein the cross-linking includes binding to hydroxyl groups on the ring-opened lactide copolymer.
