3-(4-Aminophenoxy)aniline is one of ethers-buliding-blocks. Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. Application In Synthesis of 3-(4-Aminophenoxy)anilineEthers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds.

Zaitsev, B. A.;Kleptsova, L. G.;Shvabskaya, I. D. published 《Heat-resistant network copolymers based on rolivsans modified with aromatic diamines》 in 2017. The article was appeared in 《Russian Journal of Applied Chemistry》. They have made some progress in their research.Application In Synthesis of 3-(4-Aminophenoxy)aniline The article mentions the following:

Thermochem. transformations of rolivsans with aromatic diamines were studied by IR and NMR (1H, 13C) spectroscopy and by dynamic mech., thermal, and elemental anal. The heat resistance of rolivsans is considerably enhanced by their modification with small additions (10±5%) of an aromatic diamine with curing at 150-300 (320)°C. The experimental procedure involved many compounds, such as 3-(4-Aminophenoxy)aniline (cas: 2657-87-6) .
