The influence of arylene ether positions and phenyl substituents on the physical properties of functional fluorinated polymers

Abstract

We propose four types of poly(arylene ether)s (PAEs) polymers with remarkable thermal stability and high optical transmittance. The PAEs were synthesized by means of nucleophilic displacement through polymerization on a 2-trifluoromethyl-activated bisfluoro monomer to react with bisphenols. Thermal analysis indicated that PAEs possessed a high glass-transition point of ∼300 °C and a decomposition temperature of T d=500 °C at a weight loss of 5%. In addition, a high transmittance of 92%, a low dielectric constant of ∼1.9 and the mechanical properties of PAE films were experimentally determined. The physical properties of PAEs related to the arylene ether positions and phenyl substituents, which showed great potential as substrates for flexible electronics. © The Society of Polymer Science, Japan (SPSJ) All rights reserved.
