  • Patent number: 11143591
    Abstract: A method for detecting or comparing mechanical strength of macro-molecular polymer materials. The detecting method has the steps of measuring the mechanical strength and the maximum value of the fluorescence absorption spectrum of each of the plurality of samples to form a curve relationship or function relationship between the maximum value of the fluorescence absorption spectrum and the mechanical strength; measuring the maximum value of the fluorescence absorption spectrum of the target material, and using the curve relationship or the function relationship to obtain the mechanical strength of the target material. The plurality of samples and the target material are both prepared from a macro-molecular polymer, and the macro-molecular polymer may be composed of disulfonate-difluorobenzophenone, hydroxyindole and difluorobenzophenone as monomers, and the sulfonate groups of the disulfonate-difluorobenzophenone have metal cations.

  • Patent number: 10640612
    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 ??, 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.

  • Patent number: 10119005
    Abstract: A method for recovering, regenerating and repairing polymer. The method includes immersing a polymer in an acid solution so that hydrogen ions of the acid solution replace metal cations of the polymer to obtain an acid-treated polymer, and to realize the recovery of the polymers. Subsequently, the acid-treated polymer is immersed in an alkaline solution to obtain a base-treated polymer to realize the regeneration of the polymers. The polymer is composed of disulfonate-difluorobenzophenone, hydroxyindole and difluorobenzophenone as monomers, and sulfonate groups of the disulfonate-difluorobenzophenone have metal cations. The method replaces the metal cations with hydrogen ions to realize the recovery of the polymers and reduce environmental pollutions. The regeneration of polymers is realized by replacing the hydrogen ions with the metal cation, and resource recycling. Through the process of local repair, the service life of the product of polymers can be prolonged.
