摘　　要：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 Mn 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 （Ts） of T 〉 250 ℃. Moreover, the resultant polymers were amorphous determined by wide angle X-ray diffraction （WAXD）. ？2009 Lei Wang. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
