Web1) Buna-S (styrene butadiene rubber) - It is obtained by the polymerization of Buta-1, 3 -diene and styrene in the ratio of 3:1 in the presence of sodium. It is used for making automobile tyres and footwear. 2) Buna-N (Nitrile rubber)- It is obtained by polymerization of 1,3-butadiene and acrylonitrile in the presence of a peroxide catalyst. 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-SBR). E-SBR is more widely used. Emulsion polymerization E-SBR produced by emulsion polymerization is initiated by free radicals. … 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 It is a commodity material which competes with natural rubber. The elastomer is used widely in pneumatic tires. This application mainly calls for E-SBR, although S-SBR is growing in … See more • Synthetic rubber • Nitrile rubber • Elastomer • Ozone cracking • Tire See more The material was initially marketed with the brand name Buna S.

Divide the molecular mass of the polymer by the molecular weight of the monomer. For example, if the molecular mass of tetrafluoroethylene is 1,20,000, then its degree of polymerization is calculated as 1,20,000 / 100 = 1,200. Therefore, the degree of polymerization is 1,200. code of ethics template
