“…The bis(ketonaphthalic-anhydride), IIa, was synthesized by FriedelCrafts reaction of isophthalic acid chloride with two-fold molar amounts of acenaphthene and subsequent oxidation of the obtained bis(acenaphthyl) to obtain the corresponding naphthalene tetracarboxylic acid that by anhydrization led to the corresponding dianhydride (34).…”

Oxadiazole-containing poly(naphthylimide)s were prepared by polycondensation reaction and their solid-state properties were investigated. Flexible films having good mechanical properties were made therefrom. The tougher polymer films were the subject of electrical insulating properties measurements. The dielectric constant values, measured at room temperature and in the frequency domain of 1 Hz-1 MHz, are in the range of 2.63-3.24, being lower or comparable with those of Kapton HN measured under the same conditions. The dielectric loss values are low, in the same range with those of Kapton HN. The dielectric spectroscopy data showed distinct subglass transitions for these polymers: γ relaxations with activation energies of 35 and 46 kJ/mol, and a β relaxation with the activation energy of 86 kJ/mol.

“…14,15 Polymers Poly(naphthalene-imide)s, I, have been prepared by solution polycondensation reaction at high temperature of equimolar amounts of aromatic diamines containing oxadiazole rings with naphthalene-1,4,5,8-tetracarboxylic dianhydride or bis(ketonaphthalic-anhydride) to produce polyimides Ia-Id, or with a mixture 1:1 of 6FDA and naphthalene-1,4,5,8-tetracarboxylic dianhydride/ bis(ketonaphthalic-anhydride) to obtain copolyimides Ie-Ih. The polycondensation reaction was carried out in N-methylpyrrolidinone (NMP), in the presence of benzoic acid as catalyst, at a concentration of 10-12% total solids, as shown in Scheme 1.…”

Two series of poly(oxadiazole-imide)s based on naphthalene-containing anhydrides and aromatic diamines containing preformed oxadiazole rings have been synthesized and their properties studied and compared. One series contains four polymers: two of them are based on naphthalene-1,4,5,8-tetracarboxylic dianhydride and the other two are based on bis(ketonaphthalicanhydride). The other series contains four copolymers based on mixtures of these dianhydrides with hexafluoroisopropylidenediphthalic anhydride. The thermal stability of these polymers and copolymers and their photo-optical properties in solution and solid state have been investigated.

Novel aliphatic-bridged bis(acenaphthalene)s are synthesized and evaluated as potential precursors to high-temperature reactive monomers. It was found that as the length of the aliphatic bridging unit increased, the thermal stability of bis(acenaphthalene) increased and melting point decreased. The use of an alternative route for the introduction of the reactive vinyl group resulted in a dramatic increase in monomer purity. The increase in monomer purity resulted in the creation of a processing window that enabled samples to be melt cast prior to polymerization, greatly improving their suitability as high-temperature polymers. Polymerized samples were found to have high thermal stability, indicating they have potential as high temperature materials. V V C 2005 Wiley Periodicals, Inc.
