대표청구항▼
What is claimed is: 1. A method for forming an alkenoic amide, comprising: treating a PHA to form the alkenoic amide, wherein the alkenoic amide is derived from only one repeat unit of the PHA, and the PHA is selected from the group consisting of poly 3-hydroxypropionate, poly 2-methyl-3-hydroxypro
What is claimed is: 1. A method for forming an alkenoic amide, comprising: treating a PHA to form the alkenoic amide, wherein the alkenoic amide is derived from only one repeat unit of the PHA, and the PHA is selected from the group consisting of poly 3-hydroxypropionate, poly 2-methyl-3-hydroxypropionate, and a copolymer thereof. 2. The method of claim 1, wherein the PHA is poly 3-hydroxypropionate. 3. The method of claim 1, wherein the PHA is poly 2-methyl-3-hydroxypropionate. 4. The method of claim 1, wherein the alkenoic amide is acrylamide. 5. The method of claim 1, wherein the alkenoic amide is methacrylamide. 6. The method of claim 1, wherein the PHA is derived from biomass selected from the group consisting of plant biomass and microbial biomass. 7. The method of claim 1, further comprising contacting the PHA with an amine. 8. The method of claim 7, wherein the amine is selected from the group consisting of ammonia, methyl amine, ethyl amine, and hydroxyethylamine. 9. The method of claim 1, wherein treating the PHA occurs at a temperature of less than about 100째 C. 10. The method of claim 1, wherein treating the PHA occurs at a pressure of at least about 50 psig. 11. The method of claim 1, wherein the percent yield of the alkenoic amide is at least about 50%. 12. A method for forming an alkenoic amide, comprising: treating a biomass containing a PHA to form the alkenoic amide, wherein the PHA is selected from the group consisting of poly 3-hydroxypropionate, poly 2-methyl-3-hydroxypropionate, and a copolymer thereof. 13. The method of claim 12, wherein the alkenoic amide is acrylamide. 14. The method of claim 12, wherein the alkenoic amide is methacrylamide. 15. The method of claim 12, wherein the biomass is selected from the group consisting of plant biomass and microbial biomass. 16. The method of claim 12, wherein the biomass comprises non-lyophilized biomass. 17. The method of claim 12, further comprising contacting the PHA with an amine. 18. The method of claim 17, wherein the amine is selected from the group consisting of ammonia, methyl amine, ethyl amine, and hydroxyethylamine. 19. A method for forming an alkenoic amide, comprising: heating a PHA to a temperature of at most about 100째 C to form the alkenoic amide, wherein a percent yield of the alkenoic amide is at least about 50%, and the PHA is selected from the group consisting of poly 3-hydroxypropionate, poly 2-methyl-3-hydroxypropionate, and a copolymer thereof. 20. The method of claim 19, wherein the percent yield of the alkenoic amide is at least about 60%. 21. The method of claim 19, wherein the percent yield of the alkenoic amide is at least about 70%. 22. The method of claim 19, wherein the percent yield of the alkenoic amide is at least about 80%. 23. The method of claim 19, wherein the percent yield of the alkenoic amide is at least about 90%. 24. The method of claim 19, wherein the temperature is at least about 50째 C. 25. The method of claim 19, wherein the temperature is at least about 60째 C. 26. The method of claim 19, wherein the temperature is at most about 80째 C. 27. The method of claim 19, wherein the PHA is derived from a biomass selected from the group consisting of plant biomass and microbial biomass. 28. The method of claim 19, further comprising contacting the PHA with an amine. 29. The method of claim 28, wherein the amine is selected from the group consisting of ammonia, methyl amine, ethyl amine, and hydroxyethylamine. 30. A method for forming an alkenoic amide, comprising: heating a PHA to form the alkenoic amide, wherein the PHA is selected from the group consisting of poly 3-hydroxypropionate, poly 2-methyl-3-hydroxypropionate, and a copolymer thereof. 31. The method of claim 30, wherein the alkenoic amide is acrylamide. 32. The method of claim 30, wherein the alkenoic amide is methacrylamide. 33. The method of claim 30, further comprising contacting the PHA with an amine. 34. The method of claim 33, wherein the amine is selected from the group consisting of ammonia, methyl amine, ethyl amine, and hydroxyethylamine.
