(FR) COMPOSITION DURCISSABLE D'ÉLASTOMÈRES
Abstract
(EN)
The invention pertains to compositions comprising an elastomer and a plurality of microcapsules having a cross-linked polymeric shell and a core containing at least one (per)fuoropolyether compound comprising a (per)fluoropolyoxyalkylene chain being a sequence of recurring units having at least one catenary ether bond and at least one fluorocarbon moiety.
(FR)
L'invention concerne des compositions comprenant un élastomère et une pluralité de microcapsules ayant une enveloppe polymère réticulée et un noyau contenant au moins un (per)fluoropolyéther comprenant une chaîne (per)fluoropolyoxyalkylène qui est une séquence d'unités récurrentes ayant au moins une liaison éther caténaire et au moins une fraction fluorocarbonée.
