ABSTRACT:
Novel processes are provided for synthesizing 2,2-bis(4-fluorophenyl)hexafluoropropane and the use of this synthesized monomer in polymerization reactions to form poly(arylethers) or poly(arylthioethers). Synthesis of 2,2-bis(4-fluorophenyl)hexafluoropropane involves converting the commonly available compound Bisphenol AF to an amino-substituted form, followed by treatment with borofluoric acid and a nitrite, and then an aromatic solvent to obtain the monomer. The monomer can be mixed with either a dihydroxy diphenyl hexafluoropropane or a dimercapto diphenyl hexafluorpropane to cause a nucleophilic substitution reaction, thereby yielding the desired poly(arylether) or poly(arylthioether).
