Abstract
The reaction of disodium salt of 2,2-bis(4-oxyphenyl)-1,1,1,3,3,3-hexa fluoropropane with a two-fo Id molar amount of 4-nitro-N-methylphthali mide under the conditions ensuring aromatic nucleophilic nitro-substit ution produced imido-4-oxy)phenyl]-1,1,1,3,3,3-hexafluoropropane. Its hydrolysis and subsequent dehydration yielded dianhydride of the corre sponding tetracarboxylic acid. Polycondensation of this dianhydride wi th mono-, di-, tri, or tetraphenyl aromatic diamines in m-cresol produ ced soluble aromatic polyimides with low melt viscosity.
