| titleOfInvention | A kind of aromatic diamine monomers of the structure containing dual-tert-butyl and preparation method and application |
| abstract | The invention provides a kind of aromatic diamine monomers of structure containing dual-tert-butyl, its preparation method is：Reacted in the basic conditions with parachloronitrobenzene by 9,9 pairs of (hydroxy phenyl of 3 tert-butyl group 4) fluorenes of bisphenol compound first, obtain dinitro compound 9,9 pairs [3 tert-butyl group 4 (4 nitro-phenoxy) phenyl] fluorenes；Then dinitro compound is subjected to catalysis reduction in organic solvent, obtains aromatic diamine monomers 9,9 pairs [3 tert-butyl group 4 (4 amido phenoxy group) phenyl] fluorenes.The aromatic diamine monomers of structure containing dual-tert-butyl can be applied to the preparation of soluble poly etherimide, and made PEI has good film forming, high hot property and excellent gas separating property. |
