Abstract
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.
Claims21
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.
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.
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.
