Abstract: A macro-molecular polymer and its preparation method. The macro-molecular polymer takes disulfonate-difluorobenzophenone, hydroxyindole and difluorobenzophenone as monomers for which a sulfonate group of the disulfonate-difluorobenzophenone is a metal cation. High-performance polymers can be obtained with crosslinked structure among molecular chains by a way of interaction of metal cations −π, and further to obtain a high performance polymer having good mechanical properties and stability. Furthermore, the polymer facilitates recovery and has good reproducibility and recycling properties.
