ADHESIVE COMPOSITION AND STRUCTURE COMPRISING AT LEAST ONE LAYER OF THE SAID COMPOSITION

ADHESIVE COMPOSITION AND STRUCTURE COMPRISING AT LEAST ONE LAYER OF THE SAID COMPOSITION

The invention relates to an adhesive composition comprising at least one polyamide noted A, with a mean number of carbon atoms per nitrogen atom, noted CA, of between 4 and 8.5 and advantageously between 4 and 7; at least one polyamide noted B, with a melting point of greater than or equal to 180° C...

Zusammenfassung:The invention relates to an adhesive composition comprising at least one polyamide noted A, with a mean number of carbon atoms per nitrogen atom, noted CA, of between 4 and 8.5 and advantageously between 4 and 7; at least one polyamide noted B, with a melting point of greater than or equal to 180° C. and a mean number of carbon atoms per nitrogen atom, noted CB, of between 7 and 10 and advantageously between 7.5 and 9.5; at least one polyamide noted C, with a mean number of carbon atoms per nitrogen atom, noted CC, of between 9 and 18 and advantageously between 10 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 carbon atoms per nitrogen atom of the polyamides A, B and C also satisfying the following strict inequality: CA
