buna rubber

A type of synthetic rubber based in polymerization of butadiene (buta-1,3-diene).

An improved form, known as Buna-S was developed by copolymerizing butadiene with styrene. In 1934, Buna-N was in­vented, in which the styrene was re­placed by acrylonitrile, giving a product with better oil resistance.
