This document describes a procedure for the determination of the following antidegradants in vulcanized rubbers:

  1. aminoketone group;

  2. naphthylamine group;

  3. diphenylamine group;

  4. p-phenylenediamine;

  5. 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.
