Abstract
Multilayer articles such as V-belts, hoses, rubber sheets, tires are produced from ethylene, alpha-olefin, or ethylene, alpha olefin diene copolymer elastomers which despite their attractive properties, have not been used previously due to the lack of green tack. The problem of insufficient green tack is overcome by the incorporating an aromatic containing petroleum resin.
Claims29
An article comprising a multilayer structure with at least one layer containing a blend of an ethylene, α-olefin copolymer and/or an ethylene α-olefin diene terpolymer and an aromatic-containing hydrocarbon resin.
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.
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.
