标准范围

本文件描述了硫化橡胶中以下抗降解剂的测定程序:-氨基酮基；-萘胺基；-？二苯胺基；-？对苯二胺；-？单酚类。表A.1总结了抗降解剂的类别，包括化学名称、缩写术语和CAS注册号。如果存在填充剂油，可能会产生干扰。对于聚-2,2,4-三甲基-1,2-二氢喹啉，由于其聚合物性质，该方法仅提供近似值。

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.
