Polymide Super-fiber from Soluble Polymide

Polymide Super-fiber from Soluble Polymide

We synthesized solvent-soluble polyimide which was composed from 3,3',4,4'-biphenyl tetracarboxylic acid dianhydride(BPDA), 4,4'-bis(4-amino phenoxy) biphenyl(BAPB) and bis(3-amino-4-hydroxyphenyl) sulfone(DABS). Polyimide fiber was obtained by air gap spinning of the solution. Fibers...

Zusammenfassung:We synthesized solvent-soluble polyimide which was composed from 3,3',4,4'-biphenyl tetracarboxylic acid dianhydride(BPDA), 4,4'-bis(4-amino phenoxy) biphenyl(BAPB) and bis(3-amino-4-hydroxyphenyl) sulfone(DABS). Polyimide fiber was obtained by air gap spinning of the solution. Fibers heat-treated at 200~300°C had excellent heat resistance and circle cross-section.
