ABSTRACT:
The present invention relates to terphenyl dihydroxy monomers containing fluorine and fluorinated poly(arylene ether sulfide)s prepared by using the monomers, more particularly, terphenyl dihydroxy monomers containing both two hydroxy functional groups and fluorine and fluorinated poly(arylene ether sulfide)s prepared by an aromatic nucleophilic substitution polymerization (SNAr) using the monomers, which are thus useful as optical materials in the field of information telecommunications.
