主权项 1. A method for enhancing the mechanical properties of a polyester container, the method comprising: blending a polyester with at least one gas barrier additive to form a polyester composition having an I.V. from about 0.65 dL/g to about 1.0 dL/g; and stretch blow molding the polyester composition into a polyester container; wherein the at least one gas barrier additive comprises a compound having the chemical structure of Formula I: wherein X and X6, independent of one another, comprise hydrogen, halide, heteroatom, 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; wherein s, t, u, and v, independent of one another, is a number from 0 to 10; and 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.
