There are provided a novel diarylamine compound represented by the following formula (I), (II) or (III), which has at least one signal attributable to the hydrogen of the N—H moiety at 8.30 ppm to 9.00 ppm when a deuterated dimethyl sulfoxide solution of the diarylamine compound is analyzed by 1H-NMR; and an aging inhibitor, a polymer composition, a crosslinked rubber product and a molded article thereof, and a method of producing a diarylamine compound. In the formulas, A1 to A6 each represent an aromatic group which may have a substituent; A represents an aromatic group or a cyclic aliphatic group, which may both have a substituent; L represents 1 or 2; and n represents 0 or 1.
提供了一种新的二芳基胺化合物,其由以下公式(I),(II)或(III)表示,当通过1H-NMR分析二芳基胺化合物的去氘二甲基亚磺酰溶液时,具有至少一个可归因于N-H基团的氢的信号,在8.30 ppm至9.00 ppm之间;以及一种老化抑制剂,一种聚合物组合物,一种交联橡胶产品和其模压制品,以及一种生产二芳基胺化合物的方法。在公式中,A1至A6分别表示可能具有取代基的芳基基团; A表示芳基或环状脂肪族基团,两者都可能具有取代基; L表示1或2; n表示0或1。
