ABSTRACT Novel dinitro and diamino compounds having the formula: Image wherein A is selected from the group consisting of SO2, O, S, CO, C1 to C6 alkyl, perfluoroalkyl or perfluoroarylalkyl having from 1 to 10 carbon atoms, and a carbon-carbon bond directly linking the two aromatic groups, R is selected from the group consisting of hydrogen, hydroxy and C1 to C4 alkoxy, and R' is selected from the group consisting of NO2 and NH2. In the most preferred embodiment, the A linking group selected from hexafluoroisopropylidene or 1-phenyl-2,- 2,2-trifluoroethane, and R is hydroxy. The compounds of the present invention, where R' is NH2, may be used as crosslinking agents for epoxy resins and for unsaturated elastomers, or as a reactant monomer with an organic diacid or dianhydride co-reactant monomer in the preparation of polyamide, polyimide, polyamide-imide and polybenzoxazole polymers having superior thermal and mechanical properties.
