Abstract

The invention provides an article comprising a first layer and a second layer, and wherein the first layer is formed from a first composition comprising an ethylene/α-olefin/diene interpolymer, an isoprene rubber (synthetic), a natural rubber, a butadiene rubber, a styrene butadiene rubber, a chloroprene rubber, a nitrile rubber, a hydrogenated nitrile rubber, a chlorinated polyethylene, a chlorosulfonated polyethylene, an ethylene/propylene rubber, an ethylene/diene copolymer, a fluoro rubber, a polyurethane, a silicone rubber, or a combination thereof; and wherein the second layer is formed from a second composition comprising a butyl rubber, a halobutyl rubber, polyvinylidene chloride, a brominated polymer derived from a copolymer of isobutylene and p-methyl styrene, a nitrile rubber, a chloroprene rubber, a chlorosulfonated polyethylene, a chlorinated polyethylene, a polyurethane, a fluoro rubber, or a combination thereof.

Claims (21)

1. An article comprising a first layer and a second layer, and

wherein the first layer is formed from a first composition comprising an ethylene/α-olefin/diene interpolymer, an isoprene rubber (synthetic), a natural rubber, a butadiene rubber, a styrene butadiene rubber, a chloroprene rubber, a nitrile rubber, a hydrogenated nitrile rubber, a chlorinated polyethylene, a chlorosulfonated polyethylene, an ethylene/propylene rubber, an ethylene/diene copolymer, a fluoro rubber, a polyurethane, a silicone rubber, or a combination thereof; and

wherein the second layer is formed from a second composition comprising a butyl rubber, a halobutyl rubber, polyvinylidene chloride, a brominated polymer derived from a copolymer of isobutylene and p-methyl styrene, a nitrile rubber, a chloroprene rubber, a chlorosulfonated polyethylene, a chlorinated polyethylene, a polyurethane, a fluoro rubber, or a combination thereof, and

wherein the article does not comprise a fiber reinforcing material.

2. The article of claim 1 , wherein the first composition is different from the second composition.

3. The article of claim 1 , wherein the second layer is formed with a second composition comprising a butyl rubber, a halobutyl rubber, a polyvinylidene chloride, a brominated polymer derived from a copolymer of isobutylene and p-methyl styrene, a nitrile rubber, or a combination thereof.

4. The article of claim 1 , wherein the second composition comprises a butyl rubber, a halobutyl rubber, a polyvinylidene chloride, a nitrile rubber, or a combination thereof.

5. The article of claim 1 , wherein the second composition comprises a butyl rubber, a polyvinylidene chloride, or a combination thereof.

6. The article of claim 1 , wherein the second composition comprises a butyl rubber.

7. The article of claim 1 , wherein the second composition comprises a polyvinylidene chloride.

8. The article of claim 1 , wherein the first composition comprises an ethylene/α-olefin/diene interpolymer, an isoprene rubber (synthetic), a natural rubber, a butadiene rubber, a styrene butadiene rubber, an ethylene/propylene rubber, an ethylene/diene copolymer, a silicone rubber, or a combination thereof.

9. The article of claim 1 , wherein the first composition comprises an ethylene/α-olefin/diene interpolymer, a natural rubber, a butadiene rubber, a styrene butadiene rubber, or a combination thereof.

10. The article of claim 1 , wherein the first composition comprises an ethylene/α-olefin/diene interpolymer, a styrene butadiene rubber, or a combination thereof.

11. The article of claim 1 , wherein the first composition comprises an ethylene/α-olefin/diene interpolymer.

12. The article of claim 1 , wherein the second layer is adjacent to the first layer.

13. The article of claim 1 , wherein the article further comprises a third layer formed from a third composition comprising an ethylene/α-olefin/diene interpolymer.

14. The article of claim 13 , wherein the second layer is between the first layer and the third layer.

15. The article of claim 1 , wherein the article has an Oxygen Transmission rate (OTR) less than, or equal to, 600 cc/m 2 /day at ambient atmosphere.

16. The article of claim 1 , wherein at least one composition, independently, further comprises at least one filler.

17. The article of claim 1 , wherein at least one composition, independently, further comprises at least one crosslinking agent, one crosslinking activator in combination with a fatty acid and one crosslinking accelerator.

18. The article of claim 17 , wherein the crosslinking agent is selected from the group consisting of sulfur-containing compounds, peroxides, and phenolic compounds.
