摘要: Abstract Poly(arylene ether)s consisting of aromatic rings and ether linkages form an important class high-performance polymeric material with excellent combination thermal mechanical properties. Poly(ary1ene are generally synthesized via nucleophilic substitution activated dihalide bisphenol. Fluorinated poly(arylene containing bulky –CF 3 groups especially interesting because they enhance the solubility polymers increase glass transition temperature without reducing stability. The group also serves to free volume polymer, thereby improving various properties polymer including its application as a membrane in microelectronic applications by endowing low dielectric constant. first part chapter deals synthetic strategies, characterization, general fluorinated ether)s. second gas separation pervaporation proton exchange membranes for fuel cell application.
