Molecular formula : MW : CAS :
nature : a styrene-butadiene rubber. Butadiene Styrene Monomer and butyl lithium as a catalyst in the non-polar solvent polymerization generated from the Chinese Communists. Under the polymer structure, a random type can be divided into two types, the type and block, the latter with thermoplastic (see thermoplastic elastomer). Random solution polymerization styrene-butadiene rubber, cis-1 ,4-isomer content of 35% -40%, wear and deflection, a rebound in performance such as heat than polymerization styrene-butadiene rubber, and after extrusion small contraction in the general occasions can be a substitute for emulsion styrene butadiene rubber, is particularly suitable for manufactured light-colored or transparent products, but also into oil-filled rubber shortcoming is made of wet-performance tires still poor.
