Abstract
Official abstract text for this publication.
Preforms and methods of processing 2,5-furandicarboxylic acid (FDCA) polymers, such as poly(ethylene-2,5-furandicaboxylate (PEF), to produce preforms and articles, such as containers. The present invention also includes preforms with superior processing characteristics and containers, such as PEF beverage bottles, with superior performance properties.
First claim
Opening claim text (preview).
The invention claimed is: 1. A beverage bottle made from a preform comprising a polymer comprising 2,5-furandicarboxylic acid (FDCA) and at least one diol; wherein the polymer comprises at least about 50 wt % FDCA, and wherein the preform has a (i) hoop stretch ratio of between about 5.2 and about 7.2 and (ii) an axial stretch ratio between about 2.3 and about 3.3. 2. The beverage bottle claim 1 , wherein the at least one diol is ethylene glycol. 3. The beverage bottle of claim 1 , wherein the at least one diol is bio-based. 4. The beverage bottle of claim 1 , wherein the preform has a length of between about 20 and about 400 mm. 5. The beverage bottle of claim 1 , wherein the preform has a length of between about 20 and about 50 mm. 6. The beverage bottle of claim 1 , wherein the beverage bottle is a carbonated beverage bottle. 7. The beverage bottle of claim 1 , wherein the beverage bottle has a shelf life of at least 8 weeks. 8. The beverage bottle of claim 1 , wherein the beverage bottle has a shelf life of at least 20 weeks. 9. The beverage bottle of claim 1 , wherein the beverage bottle has a shelf life of between about 20 and about 50 weeks. 10. A method of producing a bottle, comprising (i) providing a preform comprising a polymer comprising 2,5-furandicarboxylic acid (FDCA and at least one diol; wherein the polymer comprises at least about 50 wt % FDCA, and wherein the preform has (a) a hoop stretch ratio of between about 5.2 and about 7.2 and (b) an axial stretch ratio between about 2.3 and about 3.3, and (ii) forming a bottle from the preform by injection stretch blow molding, wherein the bottle is a beverage bottle. 11. The method of claim 10 , wherein the at least one diol is ethylene glycol. 12. The method of claim 10 , wherein the at least one diol is bio-based. 13. The method of claim 10 , wherein the preform has a length of between about 20 and about 400 mm. 14. The method of claim 10 , wherein the preform has a length of between about 20 and about 50 mm. 15. The method of claim 10 , wherein the bottle is a carbonated beverage bottle. 16. A method of producing a preform for injection stretch blow molding, comprising (i) providing a polymer comprising 2,5-furandicarboxylic acid (FDCA and at least one diol; wherein the polymer comprises at least about 50 wt % FDCA; (ii) injection molding the polymer to provide the preform, wherein the preform has a (a) a hoop stretch ratio of between about 5.2 and about 7.2 and (b) an axial stretch ratio between about 2.3 and about 3.3. 17. The method of claim 16 , wherein the at least one diol is ethylene glycol. 18. The method of claim 16 , wherein the at least one diol is bio-based. 19. The method of claim 16 , wherein the preform has a length of between about 20 and about 400 mm. 20. The method of claim 16 , wherein the preform has a length of between about 20 and about 50 mm. 21. The method of claim 16 , wherein the beverage bottle is a bottle for carbonated beverages.
