Rubber, raw synthetic. Determination of antidegradants by high-performance liquid chromatography1 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.
