Heterochain polyesters. Communication 56. Fluorine-containing “polyarylates”

  • Organic and Biological Chemistry
  • Published:
Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Summary

  1. 1.

    Homogeneous and mixed terephthalic, isophthalic, perfluoroadipic, and perfluorosebacic polyesters of 4,4′-(hexafluoroisopropylidene)diphenol and of 4,4′-[α-(trifluoromethyl)benzylidene]diphenol were synthesized.

  2. 2.

    The replacement of CH3 groups on the central carbon atom of dian by CF3 groups leads to a lowering of the softening points of homogeneous and mixed polyesters based on dian.

  3. 3.

    Homogeneous and mixed hexafluorodian and [(trifluoromethyl)benzylidene]diphenol polyesters form clear stable films from solution.

  4. 4.

    4,4′-[α-(Trifluoromethyl)benzylidene]diphenol was synthesized by the condensation of 2,2,2-trifluoroacetophenone with phenol.
