Reaction Steps

N,N'-Bis-(4-phenoxyphenyl)-2,3,5,6-tetrafluoroterephthalamide was prepared from p-phenoxyaniline and 2,3,5,6-tetrafluoroterephthaloyl chloride. This amide (6.0108 g, 0.0105 moles) was polymerized with terephthaloyl chloride(2.1316 g, 0.0105 moles) by the procedure of Example 27. The amounts of aluminum chloride, DMF and DCE used were 12.55 g (0.094 moles), 3.3 mL (0.042 moles) and 60 mL, respectively. The white fibrous polymer which wasobtained had the repeat unit ##STR45##
