Versuchsvorschrift

In the following Examples, 9,9-bis(3-methyl-4-aminophenyl)fluorene (OTBAF) was prepared as described in U.S. Pat. No. 4,684,678, Example 2. It was recrystallized from anhydrous dichloroethane prior to use. p-Phenylenediamine (PDA) was obtained in a sublimed, zone-refined form from Aldrich Chemical Company. 2,5-Dimethyl(p-phenylenediamine) (DMPDA) was obtained from Aldrich and recrystallized from absolute ethanol prior to use. 4,4′-(1,4-Phenylenebis(1-methylethylidene))bisbenzamine (EHPT) was obtained from Shell Chemical Company and was recrystallized from anhydrous dichloroethane prior to use. 9,9-Bis((3,5-dimethyl-4-amino)phenyl)fluorene (DM-OTBAF), 9,9-Bis[(3-ethyl-5-methyl-4-amino)phenyl)]fluorene (DE-OTBAF), and 9,9-bis[(2,5-diethyl-4-amino)phenyl]fluorene (DEAF) were prepared analogously, but using a different aniline derivative, as OTBAF, and were recrystallized prior to use. 3,3′-4,4′-Benzophenone tetracarboxylic acid dianhydride (BTDA) was purchased from Aldrich in a sublimed form. 4,4′-Oxydi(phthalic anhydride) (ODPA) was obtained from Occidental Chemical Company and purified via recrystallization from anisole. Pyromellitic dianhydride (PMDA), 2,2′-bis-((3,4-dicarboxyphenyl)-hexafluoropropane dianhydride (6FDA), 3,3′-4,4′-biphenyltetracarboxylic dianhydride (s-BPDA), and DSDA (3,3′-4,4′-diphenyl sulfone tetracarboxylic acid dianhydride) were purchased and used as received from Chriskev Company of Leawood, Kans.
