标准范围
This part of ISO 21561 specifies procedures for the quantitative determination of the microstructure ofthe butadiene and the content of styrene in solution-polymerized SBR (S-SBR) by 1H-NMR spectrometryas an absolute method and by IR spectrometry as a relative method. The styrene content is expressed inmass % relative to the whole polymer. The trans, cis and vinyl contents are expressed in mol % relativeto the butadiene. These methods are applicable only for raw rubber.
