Monomères répondant à la formule Z2C=CWX(CY2)nCN dans laquelle X représente un atome d'oxygène ou aucun atome, Z et Y représentent un atome d'hydrogène ou de fluor, W représente un atome d'hydrogène ou de fluor ou un groupement CF3; et n est un nombre entier naturel entre 0 et 10 inclus. Ces monomères permettent grâce à des procédés orignaux de copolymérisation et réticulation de préparer des élastomères nitriles fluorosulfonés présentant de très faibles températures de transition vitreuse (Tg).
