Scope

This standard specifies the method for the determination of the microstructure of monomers in styrene-isoprene-butadiene rubber (SIBR) by proton nuclear magnetic resonance spectroscopy. This standard is applicable to the determination of non-block styrene, block styrene, total styrene, butadiene 1,2-structure, butadiene 1,4-structure, isoprene 1,2-structure, Isoprene 1,4-structure and isoprene 3,4-structure content.
