【Abstract】 A new bisphenol monomer containing a naphthylene group was synthesized via a Friedel-Crafts acylation reaction followed by a demethylation reaction. Naphthylated poly(aryl ether ether ketone)(PANEEK) and naphthylated poly(aryl ether ether ketone ketone)(PANEEKK) were successfully prepared via typical nucleophilic substitution polycondensations. These two polymers exhibited excellent properties including high Tgs(above 190 ℃), good thermal stability, improved solubility, good mechanical property, low dielectric constants(~2.8 at 1 MHz) and low moisture absorptions.更多还原
