This document describes a procedure for the determination of the following antidegradants in vulcanized rubbers:— aminoketone group;— naphthylamine group;— diphenylamine group;— p-phenylenediamine;— monophenol group.The groups of antidegradants are summarized in Table A.1 with the chemical names, the abbreviated terms and the CAS registry numbers.Extender oils, when present, can interfere.For poly-2,2,4-trimethyl-1,2-dihydroquinoline, the method provides only an approximation because of its polymeric nature.
