Abstract
Official abstract text for this publication.
A process of forming a lactide copolymer includes forming a dimethylidene lactide molecule from an L-lactide molecule. The process also includes forming a functionalized lactide monomer from the dimethylidene lactide molecule. The process includes forming a mixture that includes the functionalized lactide monomer and a bisphenol A (BPA) monomer or a BPA-derived monomer. The process further includes polymerizing the mixture to form a lactide copolymer.
First claim
Opening claim text (preview).
What is claimed is: 1 . A process of forming a lactide copolymer, the process comprising: forming a dimethylidene lactide molecule from an L-lactide molecule; forming a functionalized lactide monomer from the dimethylidene lactide molecule; forming a mixture that includes the functionalized lactide monomer and a bisphenol A (BPA) monomer or a BPA-derived monomer; and polymerizing the mixture to form a lactide copolymer. 2 . The process of claim 1 , wherein the BPA-derived molecule includes bisphenol A diglycidyl ether (DGEBA). 3 . The process of claim 1 , wherein the functionalized lactide monomer includes two epoxy functional groups. 4 . The process of claim 3 , wherein the functionalized lactide monomer includes a bisthioepoxide-functionalized lactide molecule. 5 . The process of claim 3 , wherein the mixture includes the BPA monomer, and wherein the lactide copolymer includes a lactide-BPA copolymer. 6 . The process of claim 1 , wherein the functionalized lactide monomer includes a diol-functionalized lactide molecule. 7 . The process of claim 6 , wherein the mixture includes the BPA-derived molecule, the BPA-derived molecule including bisphenol A diglycidyl ether (DGEBA), and wherein the lactide copolymer includes a lactide-DGEBA copolymer. 8 . The process of claim 1 , wherein the functionalized lactide monomer includes a bisepoxide-functionalized lactide molecule. 9 . The process of claim 8 , wherein the mixture includes the BPA monomer, and wherein the lactide copolymer includes a lactide-BPA copolymer. 10 . A process of forming a ring-opened lactide copolymer, the process comprising: forming a dimethylidene lactide molecule from an L-lactide molecule; forming a functionalized lactide monomer from the dimethylidene lactide molecule; forming a mixture that includes the functionalized lactide monomer and a bisphenol A (BPA) monomer or a BPA-derived monomer; polymerizing the mixture to form a lactide copolymer; initiating a ring-opening polymerization reaction to form a ring-opened lactide copolymer from the lactide copolymer. 11 . The process of claim 10 , wherein initiating the ring-opening polymerization reaction includes chemically reacting the lactide copolymer with a tin(II) octanoate material. 12 . The process of claim 10 , wherein the functionalized lactide monomer includes a bisthioepoxide-functionalized lactide molecule, wherein the mixture includes the BPA monomer, and wherein the lactide copolymer includes a lactide-BPA copolymer. 13 . The process of claim 10 , wherein the functionalized lactide monomer includes a diol-functionalized lactide molecule, wherein the mixture includes the BPA-derived molecule, the BPA-derived molecule including bisphenol A diglycidyl ether (DGEBA), and wherein the lactide copolymer includes a lactide-DGEBA copolymer. 14 . The process of claim 10 , wherein the functionalized lactide monomer includes a bisepoxide-functionalized lactide molecule, wherein the mixture includes the BPA monomer, and wherein the lactide copolymer includes a lactide-BPA copolymer. 15 . An article of manufacture formed by a process comprising: forming a dimethylidene lactide molecule from an L-lactide molecule; forming a functionalized lactide monomer from the dimethylidene lactide molecule; forming a mixture that includes the functionalized lactide monomer and a bisphenol A (BPA) monomer or a BPA-derived monomer; polymerizing the mixture to form a lactide copolymer; initiating a ring-opening polymerization reaction to form a ring-opened lactide copolymer from the lactide copolymer; and forming an article of manufacture from the ring-opened lactide copolymer. 16 . The article of manufacture of claim 15 , wherein the article of manufacture includes an epoxy thermoset resin material. 17 . The article of manufacture of claim 15 , wherein the article of manufacture includes a coating material. 18 . The article of manufacture of claim 15 , wherein the article of manufacture includes an electrical insulator. 19 . The article of manufacture of claim 15 , wherein the article of manufacture includes a fiber-reinforced plastic material. 20 . The article of manufacture of claim 15 , wherein the article of manufacture includes a structural adhesive material.
