Abstract
Official abstract text for this publication.
Disclosed herein are compositions that include at least about 75 weight percent (wt %) alkylated lignin based on the total weight of the composition without any solvent(s). The material having a tensile strength of at least about 35 MPa, an elongation-to-break of at least about 1.5%, or both. Articles including such materials and methods of forming the same are also disclosed.
First claim
Opening claim text (preview).
The invention claimed is: 1. An article formed from a composition comprising: at least about 75 weight percent (wt %) alkylated native lignin, unalkylated native lignin, or combinations thereof based on the total weight of the composition without any solvent(s), wherein the article has an elongation-at-break of at least about 1.5%, a tensile strength of at least about 35 MPa, or both. 2. The article according to claim 1 , wherein the alkylated native lignin, unalkylated native lignin, or combinations thereof comprises ball milled lignin. 3. The article according to claim 1 , wherein the alkylated native lignin comprises methylated ball milled lignin. 4. The article according to claim 1 , wherein the composition further comprises lignosulfonate. 5. The article according to claim 1 , wherein the composition further comprises methylated lignosulfonate. 6. The article according to claim 1 , wherein the alkylated native lignin is methylated with dimethyl sulfate. 7. The article according to claim 6 , wherein the alkylated native lignin is further methylated with diazomethane. 8. The article according to claim 1 , wherein the composition further comprises a plasticizer. 9. The article according to claim 1 , wherein the composition consists essentially of alkylated native lignin or native lignin. 10. The article according to claim 1 , wherein the article is formed using solvent casting. 11. The article according to claim 1 , wherein the article is formed using melt blending, extrusion, or any combination thereof. 12. The article according to claim 1 , wherein the article has a tensile strength of at least about 35 MPa. 13. The article according to claim 1 , wherein the article has an elongation-at-break of at least about 1.5%. 14. A material formed from a composition, the composition comprising: at least about 75 weight percent (wt %) alkylated native lignin, unalkylated native lignin, or combinations thereof based on the total weight of the composition without any solvent(s), the material having a tensile strength of at least about 35 MPa and an elongation-to-break of at least about 1.5%. 15. The material according to claim 14 , wherein the material comprises alkylated native ball milled lignin, unalkylated native ball milled lignin, or combinations thereof. 16. The material according to claim 14 , wherein the composition further comprises alkylated lignosulfonate or unalkylated lignosulfonate. 17. The material according to claim 14 , wherein the material further comprises a plasticizer. 18. The material according to claim 14 , wherein the material comprises about 85 wt % alkylated native lignin, unalkylated native lignin, or combinations thereof based on the total weight of the composition without any solvent(s). 19. The material according to claim 14 , wherein the material consists essentially of alkylated native lignin.
