Vulcanized rubbers — Determination of antidegradants by high-performance liquid chromatography

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.
