摘要: 利用Friedel-Craft和去醚化反应成功地制备了具有对称取代结构的含萘双酚单体1,5-二(3-甲基)苯羰基-2,6-二羟基萘, 并且通过高温亲核取代反应制得了两种高分子量的芳香族聚合物, 对这两种新型聚合物的热性能、溶解性能、机械性能及介电常数等进行了表征.

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.

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