Carbon disulfide or carbon tetrachloride would probably work. Frankly, the two you've named are among the ones I would be least worried about using, so unless you've got a very good reason for avoiding them specifically, you're probably better off going with one of them.
epoxidised natural rubber
Difference Between Natural Rubber And Vulcanized RubberNatural rubber Vulcanized rubber(1) Natural rubber is soft and sticky Vulcanized rubber is hard and non-sticky. (2) It has low tensile strength. It has high tensile strength. (3) It has low elasticity. It has high elasticity. (4) It can be used over a narrow range of temperature (from 10° to 60°C). It can be used over a wide range of temperature (–40° to 100°C). (5) It has low wear and tear resistance. It has high wear and tear resistance. (6) It is soluble in solvents like ether, carbon, tetrachloride, petrol, etc. It is insoluble in all the common solvents.
natural rubber is more elastic than synthetic rubber
There is natural rubber, made from the latex of the rubber tree (Hevea brasiliensis).There are several manmade rubber compounds, including butyl rubber, neoprene, and nitrile rubber.
No nitrile rubber is a synthetic rubber polymer
Natural rubber, or gum rubber, is made from latex. A LOT of rubber available today is synthetic, made from petroleum. And a large amount of the gum rubber contains a percentage of synthetic rubber.
Natural rubber is easily attacked by many oils, and solvents. In the open, ozone also attacks the intermolecular bonds.

Mixing natural rubber with nitrile rubber is possible. In fact, it is quite common to mix natural rubber with other kinds of rubbers.
natural rubber is more elastic than synthetic rubber
Natural rubber is created from the sap of the Rubber Tree. In fact, that is the only thing needed from the tree to produce natural rubber.

There is no such thing as a natural rubber, rubber is man made.

because humans cannot make synthetic rubber exactly the same as natural rubber.
