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. COA of Formula: C12H12N2OEthers 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.

COA of Formula: C12H12N2OIn 2019, Zhou, Dianrui;Yuan, Lili;Hong, Weijie;Zhang, Haoyang;Hu, Aijun;Yang, Shiyong published 《Molecular design of interpenetrating fluorinated polyimide network with enhanced high performance for heat-resistant matrix》. 《Polymer》published the findings. The article contains the following contents:

Novel reactive phenylethynyl-endcapped diluents were synthesized and phys. mixed with fluorinated cooligoimides (mol. weights of 5000 g/mol) derived from 4,4′-(hexafluoroisopropylidene)diphthalic anhydride (6FDA), 2,2′-bis(trifluoromethyl)-4,4′-diamino biphenyl (TFDB) and para-phenylenediamine (p-PDA) at 25/75 M ratio, and 4-phenylethyethynylphthalic anhydride (PEPA) to formulate blends served as matrix resins for developing high-performance composites with excellent processabilities. The uncured blend shows very low min. melt viscosity (<1 Pa s) and extended process window achieved using molten solvation of reactive diluent to prevent intermol. interactions and recrystallization at higher temperature This blend was converted to interpenetrating polyimide network through thermal-curing of phenylethynyl end-groups in each constituent. The morphol., relaxation transition and mech. property were investigated as functions of mass fraction and chem. configuration of reactive diluent. The covalent incorporation of crosslink structures restricts segmental motion while backbone linkage induces strength and toughness retention. This cooperative effect endows homogeneous networks with high glass transition temperatures (435 °C) and flexural strength (130 MPa) simultaneously.3-(4-Aminophenoxy)aniline (cas: 2657-87-6) were involved in the experimental procedure.
