Abstract: A process for reducing the number of unstable end-groups in a fluorinated polymer is disclosed, said process comprising reacting a fluorinated polymer comprising unstable end-groups with fluorine in the presence of at least one (per)haloolefin comprising at least one carbon-carbon double bond and having at least one fluorine or chlorine atom on either one of the carbon atoms of said double bond. The fluorinated polymer may be selected from those polymers comprising recurring units derived from at least one ethylenically unsaturated fluorinated monomer or from fluorinated polyethers.

Abstract: The invention pertains to a composition based on a fluoroelastomer comprising nitrile or carboxylate-type cure sites and including a curing agent and a Br-containing marker having reactivity towards the said cure-sites, which can be cured so as to deliver cured parts maintaining chemically bound bromine atoms; this material, when submitted to wear/damage would hence release Br-containing contaminants, which can easily spotted via notably an on-line mass spectrometer, so as to monitor and anticipate critical failures of sealing materials based there upon.
