Title: SBR Rubber
Additional Names: Styrene-butadiene rubber; GR-S; Government Rubber Styrene
Literature References: General-purpose synthetic rubbers that were originally produced in government owned plants as GR-S. They are copolymers obtained by the polymerization of butadiene and styrene in a ratio of approx 3:1. The chains contain a random sequence of the two monomers. Very similar in composition to Buna S (I. G. Farben) , Kraton (Shell) , Solprene (Phillips Petr.) , Stereon (Firestone) . Review: P.
