Conclusions

  1. 1.

    The chemical destruction of poly-9, 9-bis-(4-hydroxyphenyl)fluorene terephthalate under the action of hexanediol, p-xylylene glycol, 9, 9-bis-(4-hydroxyphenyl)fluorene, terephthalyl chloride, and adipic and isophthalic acids was investigated.

     
  2. 2.

    Despite the high chemical stability of polyarylates under conditions corresponding to their synthesis, they are subject to alcoholysis, phenolysis, acidolysis, and exchange at the expense of the acid chloride function.

     
  3. 3.

    The rate and degree of destruction of the polarylate are determined by the nucleophilicity of the attacking agent.

     
  4. 4.

    The catalytic action of hydrogen chloride is manifested in all types of destructive processes that occur during the synthesis of polyarylates by high-temperature polycondensation.
