Abstract

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 T_gs(above 190 ℃), good thermal stability, improved solubility, good mechanical property, low dielectric constants(~2.8 at 1 MHz) and low moisture absorptions.

Key words: Poly(aryl ether ketone), High performance polymer, Dielectric constant
