Abstract

This application discloses the use of polyamide-polydiene blends to improve the oxygen reactivity in the presence of ionic polyester compatibilizers.

Claims (12)

1. A container comprising a polyamide, a polydiene compound, a transition metal compound, and a polyester comprising an ionic compatibilizer; and wherein the ratio of the amount of polyamide to the polydiene compound is in the range of 4:1 and 1000:1 and the polydiene has functional groups and at least some of these groups have reacted with the polyamide.

2. The container of claim 1 , wherein the container comprises a stretched wall.

3. The container of claim 1 , wherein the ionic compatibilizer is a sulfonated comonomer having an —SO 3 M group with M being a metal in a +1 or +2 valence state selected from the group consisting of Li, Na, Zn, Sn, Ca and K.

4. The container of claim 1 , wherein the polyamide is poly(m-xylylene adipamide).

5. The container of claim 1 , wherein the ionic compatibilizer is a sulfonated comonomer having an —SO 3 M group with M being a metal in a +1 or +2 valence state selected from the group consisting of Li, Na, Zn, Sn, Ca and K; and wherein the polyamide is poly(m-xylylene adipamide).

6. The container of claim 1 , wherein the metal of the transition metal compound is cobalt.

7. The container of claim 5 , wherein the metal of the transition metal compound is cobalt.

8. The container of claim 2 , wherein the ionic compatibilizer a sulfonated comonomer having an —SO 3 M group with M being a metal in a +1 or +2 valence state selected from the group consisting of Li, Na, Zn, Sn, Ca and K.

9. The container of claim 2 , wherein the polyamide is poly(m-xylylene adipamide).

10. The container of claim 2 , wherein the ionic compatibilizer is a sulfonated comonomer having an —SO 3 M group with M being a metal in a +1 or +2 valence state selected from the group consisting of Li, Na, Zn, Sn, Ca and K; and wherein the polyamide is poly(m-xylylene adipamide).

11. The container of claim 2 , wherein the metal of the transition metal compound is cobalt.

12. The container of claim 10 , wherein the metal of the transition metal compound is cobalt.
