Perfectly alternating poly(arylene ether ketone sulfone)'s

open access: yesPolymer Bulletin, 2000
In this study, the synthesis of perfectly alternating poly(arylene ether ketone sulfone)'s (PAEKS) via their soluble poly(arylene ether ketimine sulfone) (PAEKetS) intermediates was described. In the first stage of this procedure a new bishalide monomer, 1,1'-bis(4-fluoro(n-benzohydroxylidene aniline)) sulfone (FBHAS) was synthesized.

Thermal stability of sulfonated Poly(Ether Ether Ketone) films

open access: yesMacromolecular Materials and Engineering, 2016
Thin film and bulk, sulfonated poly(ether ether ketone) (SPEEK) have been subjected to a thermal treatment at 160–250 °C for up to 15 h. Exposing the films to 160 °C already causes partial desulfonation, and heating to temperatures exceeding 200 °C results in increased conjugation in the material, most likely via a slight cross-linking by H ...
