Two poly(aryl ether)s containing naphthyl moieties were prepared from bis(3,5-dimethyl-4-hydroxyphenyl)naphthyl methane (monomer 1) via nucleophilic aromatic substitution polycondensation with bis(4-fluorophenyl) ketone and bis(4-fluorophenyl) sulfone.The structures of these polymers were confirmed by ~1H NMR.The M_n values of the two polymers were 96,200 and 88,600, respectively.The polymers exhibited good thermal stabilities with 5%mass loss at T>400℃and high glass-transition temperature(T_g) of T>250℃.Moreover,the resultant polymers were amorphous determined by wide angle X-ray diffraction (WAXD).

Coreover, the resultant bulk were determined determined by wide angle X-ray diffraction (WAXD).
