Quick Summary

Isobutylene, also known as isobutene, is a gaseous hydrocarbon with the chemical formula C4H8. It is one of four isomers of butene. Isobutylene is produced during the cracking of petroleum and is used in the manufacturing of butyl rubber and gasoline components. Butyl rubber, a synthetic rubber, is made by copolymerizing isobutylene with small amounts of isoprene. This material is valued for its resistance to gases, chemicals, and weathering, making it useful for tire inner linings and other specialized applications.1234
