Abstract
A container comprising a polyester composition with enhanced carbon dioxide and oxygen barrier properties is provided. The polyester composition comprises a polyester and a gas barrier enhancing additive. In a particular embodiment, the gas barrier enhancing additive comprises a compound having the chemical formula: X—(X1)s—COO—(X2)t—X3—(X4)u—OOC—(X5)v—X6 or X—(X1)s—OOC—(X2)t—X3—(X4)u—COO—(X5)v—X6
Claims38
A container comprising a polyester composition comprising a polyester and a gas barrier enhancing additive, wherein the gas barrier enhancing additive comprises a compound having the chemical structure of Formula I or Formula II:
- wherein X and X6, independent of one another, comprise hydrogen, halide, heteroatom, hydroxyl, amino, amido, alkylamino, arylamino, alkoxy, aryloxy, nitro, acyl, cyano, sulfo, sulfato, mercapto, imino, sulfonyl, sulfenyl, sulfinyl, sulfamoyl, phosphonyl, phosphinyl, phosphoryl, phosphino, thioester, thioether, anhydride, oximno, hydrazino, carbamyl, phosphonic acid, phosphonato, or a C1-C10 monovalent hydrocarbon which is unsubstituted or substituted with one or more functional moieties;
- wherein X1, X2, X3, X4, and X5, independent of one another, comprise a heteroatom or a C1-C10 divalent hydrocarbon, wherein each heteroatom or C1-C10 divalent hydrocarbon is unsubstituted or substituted with one or more functional moieties or one or more C1-C10 hydrocarbyls that are unsubstituted or substituted with one or more functional moieties;
- and
- wherein s, t, u, and v, independent of one another, is a number from 0 to 10;
- wherein when X3 comprises a C6 or C10 divalent aromatic hydrocarbon, X and X6, independent of one another, comprise a hydrogen, halide, heteroatom, hydroxyl, amino, amido, alkylamino, arylamino, alkoxy, aryloxy, nitro, acyl, cyano, sulfo, sulfato, mercapto, imino, sulfonyl, sulfenyl, sulfinyl, sulfamoyl, phosphonyl, phosphinyl, phosphoryl, phosphino, thioester, thioether, anhydride, oximno, hydrazino, carbamyl, phosphonic acid, phosphonato, or a C3-C10 monovalent cyclic or heterocyclic non-aryl hydrocarbon that are unsubstituted or substituted with one or more functional moieties.
