CA 2192857
A vulcanised mixture of (i) one or more functionalised rubbers and (ii) one or more thermoplastics in a proportion sufficient for increasing the low elongation modulus, but such that the stress at failure is not reduced by more than 10 %. The thermoplastics material can be selected from polyamides and polyamide block and polyether block copolymers.
La présente invention concerne un mélange vulcanisé: (i) d'au moins un caoutchouc fonctionnalisé et (ii) d'au moins un thermoplastique en quantité suffisante pour augmenter le module aux faibles allongements mais telle que la contrainte à la rupture n'est pas diminuée de plus de 10 %. Le thermoplastique peut être choisi parmi les polyamides et les copolymères à blocs polyamides et blocs polyéther.
