Process for the preparation of poly[3,6-N-substituted carbazole-1,3,4-oxadiazole-2,5-diyl] from N-substituted carbazole-3,6-dicarboxylic acid |
| abstract |
A one-step process for the preparation of poly[3,6-N-substituted carbazole-1,3,4-oxadiazole-2,5-diyl] which comprises polymerizing N-substituted carbazole-3,6-dicarboxylic acid, wherein the carbazole nitrogen is substituted with lower alkyl of 1 to 6 carbon atoms or phenyl, with a 0 to 30% molar excess of hydrazine or a hydrazine salt of a non-oxidizing acid in the presence of polyphosphoric acid. |
