Abstract
Official abstract text for this publication.
The present disclosure relates to a composition that includeswhere R1 and R2 include at least one of a hydrogen, a hydroxyl group, and/or an alkyl group, R3 and R4 include at least one of hydrogen, a hydroxyl group, an alkyl group, and/or a ketone, and 1≤n≤2000.
First claim
Opening claim text (preview).
What is claimed is: 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.
