Synthesis and Characterization of Fluorine-containing Poly(ether ether ketone)s

Abstract

Abstract: The fluorine-containing poly(ether ether ketone)s (FPEEK) were prepared from o-fluorine hydroquinone and 4,4-difluorobenzophenone to introduce fluorine atom via nucleophilic aromatic substitution polymerization. o-Fluorine hydroquinone was synthesized through Elbs reaction. Fourier transform infrared spectra (FTIR) and nuclear magnetric resonance (1HNMR) were used to determine the structure of the monomer and polymer. Differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA), X-ray diffraction (XRD) as well as scanning electron microscopy (SEM) were used to characterize the properties of the polymer. The polymer exhibits good solubility, excellent thermal stability, low dielectric constant and low water absorption.

Key words: Fluorine-containing polymer, Solubility, Dielectric constant
