摘要: Adhesive composition comprises: polyamide A having an average carbon atoms (4-8.5, preferably 4-7) per nitrogen atom (CA); B a fusion temperature of >= 180[deg] C and number (7-10, 7.5-9.5) (CB); (9-18, 10-18) (CC), where 50 wt.% the formed by one or more polyamides A, C, mass weighted melting enthalpy in is greater than 25 J/g. J/g measured differential scanning calorimetry (DSC), (per atom) CA less CB, which CC. An independent claim included for structure comprising at least two layers, layers adhesive layer (a) constituted composition,.
