Styrene-butadiene rubber (SBR), a general-purpose synthetic rubber, produced from a copolymer of styrene and butadiene. Exceeding all other synthetic rubbers in consumption, SBR is used in great quantities in automobile and truck tires, generally as an abrasion-resistant replacement for natural rubber (produced from polyisoprene). 1  SBR is a mixture of approximately 75 percent butadiene (CH2=CH-CH=CH2) and 25 percent styrene (CH2=CHC6H5).
