Polyetherimides containing isopropylidene and hexafluoroisopropylidene groupings were obtained by the interaction of m‐phenylenediamine with the dianhydrides of 2, 2‐bis[4‐(3, 4‐dicarboxyphenoxy) phenyl]‐propane and 2, 2‐bis[4‐(3, 4‐dicarboxyphenoxy) phenyl] hexafluoropropane using high‐temperature solution polycyclocondensation in phenolic solvents. The same procedure was used for the preparation of the isopropylidene‐ and hexafluoroisopropylidene‐containing polyetherimides on the basis of 3, 3′ 4, 4′‐tetracarboxy(diphenyl ether) dianhydride and 2, 2‐bis[4‐(3‐aminopheno‐xy)phenyl] hexafluoropropane. Investigation of the polymers obtained has demonstrated that the replacement of isopropylidene groupings for hexafluoroisopropylidene fragments in polyetherimides leads to the increasing of the polymers flame‐resistance.
