Abstract: Polyamido acids derived from 4,4′-bis(4-aminophenoxy)diphenyl (diamine) and 1,3-bis(3′,4-dicarboxyphenoxy)benzene dianhydride were synthesized in two amide solvents: dimethylformamide and N-methylpyrrolidone. Fibers with different extrusion ratios were obtained by the coagulation method. These fibers were converted to polyimide… read more here.
