N,N'-Bis-(4-phenoxyphenyl)-2,6-pyridine dicarboxamide was prepared from p-phenoxyaniline and 2,6-pyridine dicarboxylic acid dichloride. The amide (8.0248 g, 0.016 moles) was polymerized with isophthaloyl chloride (3.2484 g, 0.016) using the procedure of Example 27. The amounts of aluminum chloride, DMF and DCE used were 21.33 g (0.160 moles), 4.71 mL (0.061 mol) and 100 mL, respectively. The off-white fibrous polymer which was obtained had the repeat unit ##STR46##
