Summary:The present invention relates to amorphous perfluorinated or fluorinated polymers substantially unstable ionic end group free, in particular COF, COOH or their corresponding esters, or salts or said end groups being undetectable by the method reported hereunder. Amorphous perfluorinated or fluorinated polymers containing an amount lower than 0.05 mmoles/kg polymer of each of the following ionic end groups: COF, COOH, their esters or salts, when the used determination method for said end groups is the Fourier Transform IR spectroscopy by Nicolet® Nexus FT-IR equipment (256 scannings, resolution 2 cm)
