- 83.060 Rubber
This document describes a procedure for the determination of the following antidegradants in vulcanized rubbers:
aminoketone group, ex: TMQ, ETMDQ, EDTMQ, ETMQ, ETMDQ;
naphthylamine group, ex: PAN, PANA;
diphenylamine group, ex: ODPA, SDPA, CD4, DCD;
p-phenylenediamine, ex: IPPD, 6PPD, 7PPD, DNPD, BMPPD, 77PD, DOPD, 88PD, OPPD, 8PPD, CPPD, DMHPD;
monophenol group, ex: SPH, SP, BHT, DTBMP2, DTBMOP2, DMTBP2;
Extender oils, when present, can interfere.
For poly-2,2,4-trimethyl-1,2-dihydroquinoline, the method will provide only an approximation because of its polymeric nature.
