Naphthalene-1,8-dicarboximide which is unsubstituted or substituted in the naphthalene ring is prepared by reacting naphthalene-1,8-dicarboxylic anhydride which is unsubstituted or substituted in the naphthalene ring with an ammonium salt in aqueous medium at a pH near the point of neutrality, the...
(ethylene 2,6-naphthalene dicarboxylate ester) to a temperature of about 130 ℃ to a rate of about 250 ℃ heated to produce crystalline poly (ethylene 2,6-naphthalene dicarboxylate ester), which consists of 110 reflecting the measured average apparent crystallite size of 10.0nm or greater, ...
An analysis of the copolyester fiber produced in this example revealed the presence of 4.58% bromine, an intrinsic viscosity of 0.36, a free carboxyl content of 13 meq./kg., a glass transition temperature of 76° C., and a crystalline melting point of 246° C. These data clearly show tha...
Examples of the preferable excipient include, for example, lactose, saccharose, D-mannitol, starch, crystalline cellulose, light anhydrous silicic acid, etc. Examples of the preferable lubricant include, for example, magnesium stearate, calcium stearate, talc, colloidal silica, etc. Examples of the ...

The dielectric and dynamic mechanical behaviour of amorphous poly(ethylene 2,6 naphthalene dicarboxylate) (PEN) and of thermally annealed samples is reported as a function of the morphology. During the treatment at temperatures close to the melting temperatures the samples become semi-crystalline. ...
the reaction mixture was washed twice with 20 ml of saturated sodium chloride solution and evaporated to dryness. The residue was triturated with a small amount of water to give a crystalline material. This was collected by filtration and recystallized from ethanol-diethyl ether to give 2.28 g ...
