New acetyl-containing aromatic polyether with perfluorinated mono- and biphenylene fragments

A novel fluorinated poly(arylene ether) containing tetrafluorobenzene and octafluorobenzene fragments and acetyl side groups was synthesized by polycondensation of 1,4-bis(3-acetyl-4-hydroxyphenoxy)-2,3,5,6-tetrafluorobenzene and decafluorobiphenyl. Some properties of this polymer were examined, and its keto groups were reduced into alcohol ones.
