Mechanism and kinetics of poly(ether ether ketone) (PEEK) sulfonation in concentrated sulfuric acid at room temperature. Part 3. General kinetic model of the sulfonation of PEEK fluoroarylketone chain-end repeat unit
Polymer international vol:50 issue:8 pages:932-936
The sulfonation kinetics of the fluoroarylketone chain-end repeat unit of PEEK was studied. To achieve this objective, the sulfonation reactions of a trimer, a tetramer and a polymer, each fluoroarylketone ended, were followed by F-19 NMR.
