    摘要： A negative birefringence film prepared from a poly(aryletherimide) which is the reaction product of a dianhydride and a diamine, where the dianhydride is BisADA, ODPA, BPEDA, BPQDA, BPDA, or 6FDA, alone or a mixture with one or more of: BPDA, 6FDA, BisADA, Bis-AF-DA, BPQDA, BPEDA, and ODPA; and where the diamine is 4,4′-diaminophenyl ether, 2-trifluoromethyl-4,4′-diaminophenyl ether, 2-trifluoromethyl-2′-methyl-4,4′-diaminophenyl ether, 1,4-bis(4-aminophenoxy)benzene, 4,4′-bis(4-aminophenoxy)biphenyl, 4,4′-bis(3-aminophenoxy)biphenyl, 4,4′-bis(4-aminophenoxy)terphenyl, 4,4′-bis(3-aminophenoxy)terphenyl, 2,2-bis[4-(4-aminophenoxy)phenyl]propane, 2,2-bis[4-(4-aminophenoxy)phenyl]1,1,1,3,3,3-hexafluoropropane, 1,4-bis(4-amino-2-trifluoromethylphenoxy)benzene, 2,2′-bis(trifluoromethyl)-4,4′-diaminophenyl ether (6FODA), 4,4′-bis(4-amino-2-trifluoromethylphenoxy)biphenyl (6FOBDA), 4,4′-bis(4-amino-2-trifluoromethylphenoxy)-3,3′,5,5′-tetramethylbiphenyl, 4,4′-bis(4-amino-2-trifluoromethylphenoxy)-3,3′,5,5′-tetra(tert-butyl)biphenyl, 4,4′-bis(3-amino-trifluoromethylphenoxy)biphenyl, 4,4′-bis(4-amino-2-trifluoromethylphenoxy)terphenyl, 2,2-bis[4-(4-amino-2-trifluoromethylphenoxy)-phenyl]propane, 2,2-bis[4-(4-amino-2-trifluoromethylphenoxy)-phenyl]1,1,1,3,3,3-hexafluoropropane, 1,4-bis(2-trifluoromethyl-4-aminophenoxy)-2,5-di(t-butyl)benzene (BTBDA), 3,3′-dimethyl-4,4′-diamino biphenyl (OTOL), 1,4-bis(2-trifluoromethyl-4-aminophenoxy)-2-t-butylbenzene, or mixtures thereof and wherein when a mixture of dianhydrides is present, they are present in a molar amount of between 99 to 1 (99:1) and 1 to 99 (1:99), and the film has a negative birefringence greater than 0.01, at a thickness of less than 15 μm, when the poly(aryletherimide) is solution cast or coated onto a substrate.

    摘要： New polynuclear aromatic diamines, such as 2,2′-di-(p-aminophenoxy)-biphenyl, a process for their manufacture and their use as polycondensation components for the manufacture of polyamide, polyamide-imide and polyimide polymers are described. The polymers obtained with the aromatic diamines according to the invention are readily soluble and can also be processed from the melt and are distinguished by good thermal, electrical and/or mechanical properties.
