ISO 11089:2010 PDF

ISO 11089:2010 describes a procedure for the determination of the following antidegradants in raw synthetic rubbers:

• N-alkyl-N'-phenyl-p-phenylenediamine;
• N-aryl-N'-aryl-p-phenylenediamine;
• poly-2,2,4-trimethyl-1,2-dihydroquinoline.

Extender oils, when present, can interfere.

The method, with modification if necessary, can be applied to the determination of other amine antidegradants.
