Abstract
The present invention relates to a vulcanized mixture: PA1 (i) of at least one functionalized rubber and PA1 (ii) of at least one thermoplastic in an amount which is sufficient to increase the modulus at small elongations but such that the breaking stress is not reduced by more than 10%. The thermoplastic can be chosen from polyamides and copolymers containing polyamide blocks and polyether blocks.
