Abstract:A symmetric monomer 1-chloro-4-(4-chloronaphtholsulfonyl)
   naphthalene(CCNSN) was synthesized from
   1-chloronaphthalene,chlorosulfonic acid and thionyl chloride via the
   Friedel-Crafts reaction.Four poly(aryl ether)s(named as Pa,Pb,Pc,Pd)
   containing 1-(naphthalene-1-ylsulfonyl)naphthylene moiety were then
   prepared by the nucleophilic substitution reaction of
   1-chloro-4-(4-chloronaphtholsulfonyl) naphthalene(CCNSN) with
   4,4′-isopropylidenediphenol,phenolphthalein,1,4-hydroquinone and
   4-(4-hydroxyphenyl)(2H) phthalazin-1-one,respectively.The structures of
   the monomer CCNSN and its polymers were confirmed by FT-IR,1H-NMR and
   13C-NMR.Thermal properties and crystallinity of the obtained polymers
   were studied by DSC,TGA and WAXD,respectively.Glass transition
   temperatures are in the range of 226 ℃~318 ℃ and 5% mass loss starts at
   the temperature above 450 ℃,indicating the polymers have good
   thermostability.The crystallinity of Pc from the reaction of CCNSN and
   1,4-hydroquinone is 16.7% calculated by the equation of
   crystallinity,while the other three polymers are amorphous.These
   polymers are soluble in chloroform,1,1,2,2-tetrachloro
   ethane,N,N-dimethyl aceamide and N-methyl pyrrolidione,except Pc.
