权利人:US ADMINISTRATOR OF NAT AERONA
摘要:Addition-cured polyimides that contain the reaction product of an aromatic triamine or trianhydride analogue thereof, a reactive end group such as 5-norbornene-2, 3-dicarboxylic acid, ester derivatives of 5-norbornene-2,3-dicarboxylic acid, anhydride derivatives of 5-norbornene-2,3-dicarboxylic acid, or 4-phenylethynylphthalic anhydride, an aromatic diamine, and a dialkyl ester of an aromatic tetracarboxylic acid. The resultant starlike polyimides exhibit lower melt flow viscosity than its linear counterparts, providing for improved processability of the polyimide. Also disclosed are methods for the synthesis of these polyimides as well as composite structures formed using these polyimides.

标 题 :Synthesis of asymmetric tetracarboxylic acids and corresponding dianhydrides
发明人:CHUANG CHUN-HUA
权利人:NASA
摘要:This invention relates to processes for preparing asymmetrical biphenyl tetracarboxylic acids and the corresponding asymmetrical dianhydrides, namely 2,3,3′,4′-biphenyl dianhydride (a-BPDA), 2,3,3′,4′-benzophenone dianhydride (a-BTDA) and 3,4′-methylenediphthalic anhydride (-MDPA). By cross-coupling reactions of reactive metal substituted o-xylenes or by cross-coupling o-xylene derivatives in the presence of catalysts, this invention specifically produces asymmetrical biphenyl intermediates that are subsequently oxidized or hydrolyzed and oxidized to provide asymmetric biphenyl tetracarboxylic acids in comparatively high yields. These asymmetrical biphenyl tetracarboxylic acids are subsequently converted to the corresponding asymmetrical dianhydrides without contamination by symmetrical biphenyl dianhydrides.

摘要:Methods of synthesis and application thereof for peripherally aromatic silsesquioxanes featuring reactive functionality. A method, according to one embodiment of the invention, includes reacting a polyhedral oligomeric silsesquioxane with an anhydride. The polyhedral oligomeric silsesquioxane has an inorganic core, a phenyl moiety or an anlyine moiety covalently coupled to the at least one T-type silicon atom; and a metal-aniline group or a para-aniline group covalently coupled to the at least one D-type or M-type silicon atom. The inorganic core includes 6-14 silicon atoms, at least one of the silicon atoms being an M-type silicon atom or a D-type silicon atom, and at least one of the silicon atoms being a T-type silicon atom, and 9-20 oxygen atoms.
