Abstract

The present disclosure relates to a composition that includes a structure that includes where R 1 includes at least one of a carbon atom and/or an oxygen atom, R 2 includes at least one of a carbon atom and/or an oxygen atom, and represents a covalent bond. In some embodiments of the present disclosure, the composition may be bioderived.

Claims (18)

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.
