Abstract
A method for stabilizing a composition made from PAEK, said method including a step of incorporating a stabilizing agent against thermo-oxidation phenomena, said method being characterized in that said incorporated stabilizing agent is a phosphate salt, or a mixture of phosphate salts. The phosphate salt is incorporated into the composition based on PAEK by one of the following techniques: dry blending, compounding, wet impregnation or during the process for synthesizing the PAEK polymer.
