Scope

This standard specifies the determination method for the content of the following antioxidants in synthetic raw rubber: N-alkyl-N'-phenyl-p-phenylenediamine; N-aryl-N'-aryl-p-phenylenediamine; N- Phenyl β-anthylamine; 2,2,4-trimethyl-1,2-dihydroquinoline polymer. This standard applies to chloroprene rubber (CR), nitrile rubber (NBR), styrene-butadiene rubber (SBR) and other raw rubber. When raw rubber contains extender oil, it will affect the measurement results. If necessary, this method can be slightly modified for the determination of other amine antioxidants.
