Abstract
Tetranitro aryl ether compounds are prepared by aromatic nucleophilic substitution of various aryl diols with 4-fluoro-1,2-dinitrobenzene. By reducing the nitro moieties of the tetranitro compounds, tetraamino aryl ether compounds are obtained. These latter compounds are useful as monomers in preparing thermally stable polymers having good solubility parameters.
Claims14
