NEN-ISO 21561-1

Styrene-butadiene rubber (SBR) - Determination of the microstructure of solution-polymerized SBR - Part 1: 1H-NMR and IR with cast-film method

active, Most Current
Organization: NEN
Publication Date: 1 July 2015
Status: active
Page Count: 25
ICS Code (Rubber): 83.060
scope:

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