Abstract

A series of fluorinated polyetherketones containing perfluoroaryl moieties was prepared by solution condensation polymerization. The synthesis involves the condensation of a dialkali metal salt of a bisphenol with decafluorobenzophenone. The reaction is rapid, free of side reactions, and yields polymers with high glass transition temperatures (T(g)s) and excellent thermal stability. The T(g)s of the polymers ranged from 155 to 223 degrees C as measured by differential scanning calorimetry (d.s.c.). The dynamic mechanical thermal analysis of the polymersis also described. The dielectric constants of the polymers were characterized as a function of percent relative humidity. All of the fluorinated aromatic polyetherketones were processable from solution, to yield transparent, flexible films. (C) 1997 Elsevier Science Ltd.
