Primary Uses
- Polymerized to produce synthetic rubber. While polybutadiene itself is a very soft, almost liquid material, polymers prepared from mixtures of butadiene with styrene or acrylonitrile, such as ABS, are both tough. and elastic. Styrene-butadiene rubber is the material most commonly used for the production of automobile tires
- Butadiene is also used as an organic synthesis reagent, make nylon via the intermediate adiponitrile, other synthetic rubber materials such as chloroprene, and the solvent sulfolane.
- Used in the industrial production of 4-vinylcyclohexene via a dimerization reaction and cyclododecatriene via a trimerization reaction.
