Procedure

The mixture from Example 10 (250 mg) and bis[4-(3-aminophenoxy)phenyl]sulfone (p-BAPS) (12.5 mg) were placed in an aluminum pan treated with a high temperature mold release. The mixture was heated at 350° C. with stirring and held at that temperature until the mixture became too viscous to stir easily. A glass pipette was inserted into the mixture and pulled out resulting in the formation of fibers. The fibers were heat treated at 200° C. for 2 hr, 250° C. for 12 hr in air and 300° C. for 4 hr, 350° C. for 2 hr and 375° C. for 4 hr under argon. The fibers were further carbonized by heating under argon to 1000° C. at 0.3° C./min.
