Novel dinitro and diamino compounds having the formula:
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 is 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.
具有以下式子的新型二硝基和二氨基化合物
其中 A 选自具有 1 至 10 个碳原子的 SO₂、O、S、CO、C₁ 至 C₆ 烷基、全氟烷基或全氟芳基组成的组、R 选自氢、羟基和 C₁ 至 C₄ 烷氧基组成的组,R′ 选自 NO₂ 和 NH₂ 组成的组。
在最优选的实施方案中,A 连接基团选自六氟异亚丙基或 1-苯基-2,-2,2-三氟乙烷,R 是羟基。
本发明的化合物(其中 R′为 NH₂)可用作环氧树脂和不饱和弹性体的交联剂,或在制备具有优异热性能和机械性能的聚酰胺、聚酰亚胺、聚酰胺-酰亚胺和聚苯并恶唑聚合物时用作与有机二酸或二酸酐共反应单体的反应单体。
