Abstract
(EN)
The invention pertains to a peroxide curable perfluoroelastomer comprising: - recurring units derived from tetrafluoroethylene (TFE); - recurring units derived from perfluoroethylvinylether (EVE), in an amount of between 2 and 17 % by moles, with respect to total recurring units derived from TFE, perfluoromethylvinylether (MVE) and EVE; and - recurring units derived from perfluoromethylvinylether (MVE), in an amount of between 23 and 35 % by moles, with respect to total recurring units derived from TFE, perfluoromethylvinylether (MVE) and EVE, to a process for its manufacture and to its use for the manufacture of cured articles.

L'invention concerne un perfluoroélastomère pouvant être durci en présence d'un peroxyde, comprenant : des motifs répétitifs dérivant du tétrafluoroéthylène (TFE) ; des motifs répétitifs dérivant du perfluoroéthylvinyléther (EVE) en une quantité de 2 % à 17 % en mole par rapport au nombre total de motifs répétitifs dérivant du TFE, du perfluorométhylvinyléther (MVE) et de l'EVE ; et des motifs répétitifs dérivant du perfluorométhylvinyléther (MVE) en une quantité de 23 % à 35 % en mole par rapport au nombre total de motifs répétitifs dérivant du TFE, du perfluorométhylvinyléther (MVE) et de l'EVE. L'invention concerne également un procédé de fabrication de ce perfluoroélastomère et son utilisation pour fabriquer des articles durcis.
