Abstract

The present disclosure relates to a composition that includes where R 1 and R 2 include at least one of a hydrogen, a hydroxyl group, and/or an alkyl group, R 3 and R 4 include at least one of hydrogen, a hydroxyl group, an alkyl group, and/or a ketone, and 1≤n≤2000.

Claims (16)

1. A composition comprising:

at least one of

wherein 1<n≤2000.

2. The composition of claim 1 , further comprising an end-group derived from an alcohol.

3. The composition of claim 1 , wherein the composition is bioderived as determined by ASTM-D6866.

4. A method comprising:

a first reacting of a diether with a diol to form a polymer comprising

at least one of

wherein 1<n≤2000.

5. The method of claim 4 , further comprising:

a second reacting of a cyclic ketone with an alcohol to form the diether, wherein:

the second reacting is performed prior to the first reacting.

6. The method of claim 5 , wherein the first reacting produces the alcohol.

7. The method of claim 5 , further comprising:

prior to the second reacting, separating the cyclic ketone from a mixture comprising compounds derived from catalytic fast pyrolysis.

8. The method of claim 4 , wherein the separating comprises at least one of distillation or liquid-liquid separation.
