NOVEL DIARYLAMINE COMPOUND, AND ANTI-AGING AGENT, POLYMER COMPOSITION, CROSSLINKED RUBBER PRODUCT AND MOLDED ARTICLE THEREOF, AND METHOD FOR PRODUCING DIARYLAMINE COMPOUND

摘要

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.
