Synthesis and Properties of a Novel Kind of PEAK(Poly Aryl Ether Ketone) with Lower Dielectric Constant

Abstract

Abstract: A novel monomer [2-(4-phenoxyphenyl)-1,4-diphenol] was synthesized. A novel polymer(4-phenoxyphenyl)PAEK was successfully synthesized with this new type of diphenol and 4,4'-difluorobenzophenone in TMSO. The ¹H NMR and IR characterizations of the monomer and polymer were described. Some properties of the polymer were also given out. It keeps good properties of PEEK(poly ether ether ketone)(Tg is 407 K and TGA plot shows that the weight loss of the monomer is 5% at 320 ℃ and 10% at 347 ℃) and also has better solubility, lower dielectric constant 2.9 at 1 MHz and lower dielectric loss 4.49×10^-3 at 1MHz. This kind of novel non-fluorinated PAEK(poly aryl ether ketone) with anisomerous big side group is very promising for electronic applications

Key words: Phenoxyphenyl side group, Poly aryl ether ketone(PAEK), Dielectric constant
