Reaction Steps
N,N'-Di-(4-phenoxyphenyl)hexafluoroglutaramide was prepared by reaction of p-phenoxyaniline with hexafluoroglutaroyl chloride. This amide (6.0319 g, 0.0105) was polymerized with terephthaloyl chloride (2.1624 g, 0.01065 moles), with p-phenoxybenzophenone (0.1646 g, 0.0006 moles) as capping agent and using the procedure of Example 27. The amounts of aluminum chloride, DMF and DCE used were 12.49 g (0.0937 moles), 3.3 mL (0.0426 moles) and 50 mL, respectively. The polymer which was obtained as white powdery flakes had the repeat unit ##STR42##
