摘要：

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 T(g)s (above 190 degrees C), good thermal stability, improved solubility, good mechanical property, low dielectric constants (similar to 2.8 at 1 MHz) and low moisture absorptions.
