1. A stretch blow molded container having a Barrier Improvement Factor of at least about 1.05 and comprising a polyester composition having an I.V. from about 0.65 dL/g to about 1.0 dL/g, wherein the polyester composition comprises a polyester and a gas barrier additive, wherein the gas barrier addi
1. A stretch blow molded container having a Barrier Improvement Factor of at least about 1.05 and comprising a polyester composition having an I.V. from about 0.65 dL/g to about 1.0 dL/g, wherein the polyester composition comprises a polyester and a gas barrier additive, wherein the gas barrier additive comprises a compound having one of the following chemical structures: 2. The container of claim 1, wherein the gas barrier additive comprises a compound having one of the following chemical structures: 3. The container of claim 1, wherein the gas barrier additive comprises a compound having one of the following chemical structures: 4. The container of claim 1, wherein the gas barrier additive comprises a compound having one of the following chemical structures: 5. The container of claim 1, wherein the gas barrier additive is present in the polyester composition in an amount in the range of about 0.1 to about 10 weight percent of the polyester composition. 6. The container of claim 1, wherein the polyester comprises polyethylene terephthalate. 7. The container of claim 1, wherein the polyester composition comprises a poly(ethylene terephthalate) based copolymer having less than 20 percent diacid, less than 10 percent glycol modification, or both, based on 100 mole percent diacid component and 100 mole percent diol component. 8. The container of claim 1, wherein the polyester composition comprises a polyester made using at least one first polycondensation catalyst selected from the group consisting of metals in groups 3, 4, 13, and 14 of the Periodic Table and comprising a catalyst residue remaining in the polyester from formation of the polyester, the catalyst residue comprising at least a portion of the at least one first polycondensation catalyst. 9. The container of claim 1, further comprising a creep control agent, wherein the creep control agent comprises a compound having the chemical structure: wherein R1, R2, R3, and R4, independent of one another, may comprise a heteroatom, a tetravalent carbon atom, or a C1-C3 divalent or trivalent hydrocarbon; wherein each heteroatom, tetravalent carbon atom, or C1-C3 divalent or trivalent hydrocarbon may be unsubstituted or substituted with one or more functional moieties or one or more C1-C10 hydrocarbyls that may be unsubstituted or substituted with one or more functional moieties;wherein i, ii, iii, iv, v, and vi, independent of one another, comprise a single, double, or triple bond; wherein when i is a double bond, ii and vi are single bonds; wherein when ii is a double bond, i and iii are single bonds; wherein when iii is a double bond, ii and iv are single bonds; wherein when iv is a double bond iii and v are single bonds; wherein when v is a double bond, iv and vi are single bonds; wherein when vi is a double bond, i and v are single bonds; wherein vii may be a single bond, double bond, or no bond at all connects R3 and R4;wherein m, n, o, and p, independent of one another, may be 0 or 1; wherein when m is 0, bonds ii and iii form a single continuous bond; wherein when n is 0, bonds vi and v form a single continuous bond; wherein when o is 0, R4 is bonded to R1 by a single bond; and wherein when p is 0, R3 is bonded to R2 by a single bond. 10. The container of claim 1, further comprising a creep control agent, wherein the creep control agent comprises a compound having the chemical structure: wherein A1, A2, R8, R9, and R10, independent of one another, may comprise a heteroatom, a tetravalent carbon atom, a C1-C10 divalent or trivalent hydrocarbon, or a C1-C10 hydrocarbyl that may be unsubstituted or substituted with one or more functional moieties; wherein each heteroatom, tetravalent carbon atom, or C1-C10 divalent or trivalent hydrocarbon may be unsubstituted or substituted with one or more functional moieties or one or more C1-C10 hydrocarbyls that may be unsubstituted or substituted with one or more functional moieties; wherein m′, n′, and p′, independent of one another, may be 0 or 1;wherein i, ii, and iii, independent of one another may be a single bond or a double bond;wherein t, u, v, and w, independent of one another may be a single bond, double bond, or triple bond; andwherein q, r, and s may be from 0 to 10,000. 11. The container of claim 1, further comprising a creep control agent, wherein the creep control agent comprises a compound having one of the following chemical structures: 12. A polyester composition comprising a polyester and a gas barrier additive, wherein the polyester composition has a Barrier Improvement Factor of at least about 1.05 and an I.V. from about 0.65 dL/g to about 1.0 dL/g, and wherein the gas barrier additive comprises a compound having one of the following chemical structures: 13. The polyester composition of claim 12, wherein the gas barrier additive comprises a compound having one of the following chemical structures: 14. The container of claim 1, further comprising a creep control agent.
