It appears, at least to me, that the questioner wishes for a list of elastomers that are either solvent-resistant, age-resistant (whatever that means) or both. He presents these elastomers: natural rubber
styrene-butadiene polymers (actually "styrene-butadiene-styrene" modified bitumen)
nitrile rubber
butyl rubber
neoprene
polysulfide rubber
silicone
polyurethane
I'm not sure what he's asking. Is he just doing "research," or is he actually attempting to build something? Anyway, here's what I know: Natural rubber isn't resistant to anything. And these days, you really won't find unalloyed natural rubber unless it's in a condom; they like to cut it with polyurethane to make it more durable. SBS modified bitumen, and its cousin atactic polypropylene modified bitumen, are used in roofing. They are very age-resistant (because you don't want to go back up on the roof every year) but as for solvents? Not sure. Neoprene is another good stable rubber. It will work well for you. Not sure what polysulfide is, sorry. Silicones and polyurethanes are both very chemical-proof and highly age-resistant. Polyurethane is a better product, in that the adhesive characteristics are many times better, but it's more expensive. Hope this helps. You are going to have to break it down a little. If you are asking are any of these "natural rubber" the answer is no. if you want to know about the polymers, be a little more specific and what you are using it for. Also age resistant is relevent. Mose epdm's will bloom in a year or less but it doesn't hurt the hose. Chemavic's on the other hand don't have that, they are used more for gas and chemical applications. If you break your question down into a list and your application I can probably help you better.
Another answer: I don't understand your question o_O
Yes it is Fuel Resistant
Yes it is Fuel Resistant
Butadiene is a non-corrosive gas that condenses to a liquid and is used to make polymers. Butadiene polymers include neoprene, styrene-butadiene rubber, and nitrile rubber.
No it isn't. Neoprene rubber is synthesized from materials that, when combined, act like rubber but don't have the same molecular structure. No, it does not. Neoprene is a synthetic material created by DuPont. It is made via a chemical process that starts with chloroprene. Chloroprene is made from butadiene and chlorine.

The Zebra skin Razr case is made of neoprene, so will protect from minor bumps and electrical shock.
Neoprene
Neoprene was invented by Wallace Carothers and Dupont Labs in 1930.
Neoprene
The monomer of neoprene is 2-chlorobuta-1,3-diene (C4H5Cl).
