Herein are disclosed modified vinyl alcohol polymers (mPVOH) , wherein the mPVOH can comprise structure VII: and at least one structure comprising structure IX: or structure X: wherein--R can independently comprise an unsubstituted hydrocarbon moiety comprising at least one alpha hydrogen or a substituted hydrocarbon moiety comprising at least one alpha hydrogen. The mPVOH can be useful in oxygen barrier applications, such as a forming an oxygen barrier layer of a packaging article. Also disclosed are methods of forming mPVOH and methods of using mPVOH to make packaging articles with a superior barrier to entry by atmospheric oxygen.

What is claimed is: 1. A composition, comprising a modified ethylene vinyl alcohol copolymer comprises structure V and structure VI: and at least one structure comprising structure IX or structure IV: wherein--R comprises an unsubstituted hydrocarbon moiety having structure II: wherein q1, q2, q3, q4, and r independently comprise hydrogen, methyl, or ethyl; m is--(CH 2)n--, wherein n is an integer from 0 to 4, inclusive; and, when r is hydrogen, at least one of q1, q2, q3, and q4 is also hydrogen, wherein x is greater than or equal to 1, y is greater than or equal to 1 and z is greater than or equal to 1, and the copolymer comprises from about 27 mole % to about 48 mole % ethylene. 2. The composition of claim 1, comprising structures IV, V, and VI: wherein y is greater than or equal to 1, z is greater than or equal to 1, n is 1, and q1, q2, q3, q4 , and r are hydrogen. 3. The composition of claim 1, further comprising a transition metal catalyst. 4. The composition of claim 3, wherein the transition metal catalyst is a cobalt salt. 5. The composition of claim 4, wherein the cobalt salt comprises cobalt oleate, cobalt stearate, or cobalt neodecanoate. 6. The composition of claim 1, further comprising a photoinitiator. 7. The composition of claim 1, wherein the composition is a blend comprising the modified ethylene vinyl alcohol copolymer and an oxygen barrier polymer. 8. The composition of claim 7, wherein the oxygen barrier polymer is an unmodified ethylene vinyl alcohol copolymer. 9. The composition of claim 7, wherein the blend comprises from about 5 wt % to about 20 wt % modified ethylene vinyl alcohol copolymer.
