Web5.3.3 Styrene rubber. Poly (styrene-butadiene-styrene), or SBS, is a hard rubber that is used for products like the soles of shoes, tire treads, and other places where durability is important. It is a type of copolymer called a block copolymer. Its backbone chain is made up of three segments. WebBromobutyl rubber (BIIR) is produced via the bromination of butyl rubber (IIR), which brings active C Br bonds into the polymer. BIIR has not only the same advantages as IIR (excellent gas tightness and chemical stability), but also better performance on vulcanizing and compounding than that of IIR [1-4].
