Butadiene
Description
A colorless, flammable gas obtained from petroleum, acetylene or from ethanol. Butadiene polymerizes readily in the presence of oxygen to form a rubbery polymer. It was first polymerized in Russia by Sergei Lebedev in 1910. By the 1930s, many countries developed butadiene production capabilities as a replacement for natural rubber. Currently, butadiene is primarily used as a starting material for synthetic elastomers.
See Buna, ABS resin, neoprene, and polybutadiene.
