Abstract
The invention relates to an adhesive composition comprising at least one polyamide A, with a mean number of carbon atoms per nitrogen atom (C/N), noted C, of between 4 and 8.5; at least one polyamide B, with a melting point of greater than or equal to 180° C. and a mean number C/N, noted C, of between 7 and 10; at least one polyamide C, with a mean number C/N, noted C, of between 9 and 18; at least 50% by weight of the said composition being formed from one or more polyamides chosen from polyamides A, B and C, the mass-weighted mean of the heats of fusion of these polyamides in the said composition being greater than 25 J/g (DSC), the mean number of C/N of the polyamides A, B and C satisfying the following strict inequality: C<C<C, and also to multilayer structures.
