Polyimide Fibers Obtained by Spinning Lyotropic Solutions of Rigid-Rod Aromatic Poly(amic ethyl ester)s

Fibers were spun from a lyotropic solution of a high‐molecular‐weight (η = 5.89 g · dL−1), rigid‐rod, fully aromatic polyimide precursor polymer in a dry‐jet, wet‐spinning process in NMP. Acetone was identified as the coagulant of choice since fibers could be drawn extensively in this solvent, resul...
