ISO 11089:2010描述了测定生合成橡胶中以下抗降解剂的方法:
N?烷基-N’?苯基-p?苯二胺;
N?芳基-N’?芳基-p?苯二胺;
保利?2,2,4?三甲基-1,2?二氢喹啉。
当存在时,填充油会产生干扰。
该方法经必要修改后可应用于其他胺类抗降解剂的测定。
ISO 11089:2010 describes a procedure for the determination of the following antidegradants in raw synthetic rubbers:
N?alkyl-N'?phenyl-p?phenylenediamine;
N?aryl-N'?aryl-p?phenylenediamine;
poly?2,2,4?trimethyl-1,2?dihydroquinoline.
Extender oils, when present, can interfere.
The method, with modification if necessary, can be applied to the determination of other amine antidegradants.
