Vulcanized rubbers -- Determination of antidegradants by high-performance liquid chromatography
Autor: ISO
Código ICS: 83.060


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.
