First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising: a structure represented by Formula (I): and a glass transition temperature between 60° C. and 130° C., wherein: R 1 comprises at least one of a carbon atom or an oxygen atom, R 2 comprises at least one of a carbon atom or an oxygen atom, and represents a covalent bond. 2. The composition of claim 1 , wherein the composition is bioderived. 3. The composition of claim 1 , wherein R 2 comprises a hydrocarbon chain having between 1 and 10 carbon atoms. 4. The composition of claim 3 , wherein the hydrocarbon chain is a straight chain. 5. The composition of claim 3 , wherein the hydrocarbon chain is saturated. 6. The composition of claim 3 , wherein the hydrocarbon chain further comprises at least one of a hydroxyl group, a carboxylic acid group, a glycidal ether, or an aromatic. 7. The composition of claim 1 , wherein the structure is represented by at least one of Formulas (II), (III), (IV), (V), (VI), or (VII): 8. The composition of claim 1 , wherein the structure is represented by at least one of Formulas (VIII), (IX), or (X): 9. The composition of claim 1 , wherein the structure is represented by at least one of Formulas (XI), (XII), (XIII), (XIV), (XV), or (XVI): 10. The composition of claim 9 , wherein the structure is represented by Formula (XVII): 11. The composition of claim 1 , further comprising a storage modulus between 10 MPa and 140 MPa. 12. The composition of claim 1 , further comprising an ultimate tensile modulus between 45 MPa and 75 MPa. 13. The composition of claim 1 , further comprising at least one of a fiber or a particle such as a glass fiber, a carbon fiber, or a carbon black particle.
