The styrene/butadiene ratio influences the properties of the polymer: with high styrene content, the rubbers are harder and less rubbery. SBR is not to be confused with the thermoplastic elastomer, styrene-butadiene block copolymer, although being derived from the same monomers. See more Styrene-butadiene or styrene-butadiene rubber (SBR) describe families of synthetic rubbers derived from styrene and butadiene (the version developed by Goodyear is called Neolite ). These materials have good See more The material was initially marketed with the brand name Buna S. Its name derives Bu for butadiene and Na for sodium (natrium in several languages including Latin, German, and … See more SBR is a replacement for natural rubber. It was originally developed prior to World War II in Germany by chemist Walter Bock in 1929. Industrial manufacture began during World War II, and was used extensively by the U.S. Synthetic Rubber Program to … See more SBR is derived from two monomers, styrene and butadiene. The mixture of these two monomers is polymerized by two processes: from solution (S-SBR) or as an emulsion (E … See more It is a commodity material which competes with natural rubber.
