BS ISO 11089:2010

Rubber, raw synthetic. Determination of antidegradants by high-performance liquid chromatography. | Status: Confirmed, Current

1 Scope This International Standard 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.
