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