Synthesis and characterization of novel poly(aryl ether)s containing naphthyl moieties

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 °C and high glass-transition temperature (Tg) of T > 250 °C. Moreover, the resultant polymers were amorphous determined by wide angle X-ray diffraction (WAXD).
