摘要:
Amorphous (per)fluorinated polymers containing an amount lower than 0.05 mmoles/kg polymer of each of the following ionic end groups: COF, COOH, their amidic derivatives, esters or salts, when the used determination method for said end groups is the IR spectroscopy by Nicolet® Nexus FT-IR equipment (256 scannings, resolution 2 cm -1 ).
