- 7. The article of claim 3 in which the diene is cyclopentadiene, 1-4-hexadiene, 5-methylene-2-norbomene, 5-ethylidene-2-norbomene or vinyl norbomene.
- 8. The article of claim 4 in which the diene is cyclopentadiene, 1-4-hexadiene, 5-methylene-2-norbornene, 5-ethylidene-2-norbomene or vinyl norbomene.
- 9. The article of claim 5 in which the diene is cyclopentadiene, 1-4-hexadiene, 5-methylene-2-norbornene, 5-ethylidene-2-norbornene or vinyl norbomene.
- 10. The article of claims 1 or 2 in which the terpolymer contains from 0.5 to 15 wt % of the diene.
- 11. The article of claims 1 or 2 in which the resin containing layer contains from 1 to 25 wt % of the resin.
- 12. The article of claims 1 or 2 containing from 4 to 15 wt % of the resin.
- 13. The article of claims 1 or 2 in which the aromatic containing hydrocarbon resin contains from 3% to 75% aromaticity in terms of styrene equivalents.
- 14. The article of claim 9 in which the resin is a blend of an aliphatic resin and an aromatic containing resin.
- 15. The article of claim 10 in which the resin is totally aromatic.
- 16. The article of claims 1 or 2 which also contains a rosin ester, a polyterpene, or both.
- 17. The article of claims 1 or 2 further containing a vulcanising agent for the rubber.
- 18. The article of claims 1 or 2 produced by co-extrusion.
- 19. The article of claims 1 or 2 which has been vulcanized.
- 20. The article of claim 14 in which the article is a V-belt.
- 21. The article of claim 15 in which the article is a V-belt.
- 22. The article of claim 14 in which the article is a tire.
- 23. The article of claim 15 in which the article is a tire.
- 24. The article of claim 14 in which the article is a hose.
- 25. The article of claim 15 in which the article is a hose.
- 26. The article of claim 14 in which the article is sheeting.
- 27. The article of claim 15 in which the article is sheeting.
- 28. The use of an aromatic containing hydrocarbon resin for the development of green tack in ethylene α-olefin copolymer and/or ethylene, α-olefin diene copolymer rubbers.
- 29. A process for the production of a rubber compound in which an ethylene, α-olefin copolymer rubber and/or an ethylene, α-olefin diene terpolymer rubber is compounded with additives and an aromatic hydrocarbon resin in which the rubber is first compounded with other added additives and the aromatic hydrocarbon resin added no sooner than half way through the compounding cycle.
