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. Reference 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.

Liu, Limin;Li, Jianying;Yan, Tao;Cai, Mingzhong published 《Novel preparation of poly(arylene ether sulfone amide)s via supported palladium-catalyzed carbonylative polymerization》. The research results were published in《Polymer Bulletin (Heidelberg, Germany)》 in 2020.Reference of 3-(4-Aminophenoxy)aniline The article conveys some information:

Two new aromatic diiodides with ether-sulfone linkages were synthesized via a 1-step procedure. Poly(arylene ether sulfone amide)s were synthesized by a supported Pd-catalyzed polycondensation of aromatic diiodides having ether-sulfone linkages, aromatic diamines, and CO. Polycondensation reactions were conducted in N,N-dimethylacetamide using a magnetic nanoparticles-bound Pd(II) complex [Fe3O4@SiO2-2P-PdCl2] as the catalyst and 1,8-diazabicycle[5,4,0]-7-undecene as the base at 120°, yielding poly(arylene ether sulfone amide)s having inherent viscosities of 0.43-0.77 dL/g. The resulting polymers were soluble in polar aprotic solvents and showed glass transition temperatures in the 204-265° range, with 10% weight losses occurring at temperatures >456° in N. Most of the polymers afforded transparent and tough films by solution-casting with tensile strengths of 71.8-82.2 MPa, Young’s moduli of 1.77-2.35 GPa, and elongations at break of 9.3-13.4%. More importantly, this supported Pd catalyst can facilely be separated from the product by simply using an external magnetic field and reused at least 7 times with almost consistent activity.3-(4-Aminophenoxy)aniline (cas: 2657-87-6) were involved in the experimental procedure.
