COMPOSITION FOR THERMOPLASTIC ADHESIVE, THERMOPLASTIC ADHESIVE, METHODS FOR PRODUCING SAME AND USES THEREOF

摘要

The invention relates to a composition for thermoplastic adhesive, said composition comprising an aqueous dispersion of at least one branched copolyamide with unsaturated ends, in the form of particles such that the volume mean diameter d50 of said particles is less than or equal to 50µm, and comprising more than 50mol% of amine ends out of the total number of moles of amine and acid ends of said branched copolyamide with unsaturated ends, of which certain of said amine ends are at least partially neutralised by a Bronsted acid made from phosphorus such that the molar ratio between [Bronsted acid]/[amine ends] is between 0.1 and 5, said composition further comprising at least one initiator for crosslinking said 1 branched copolyamide with unsaturated ends. The invention also relates to a preparation method and to the uses for such a composition. The invention finally relates to a method for producing a thermoplastic adhesive and to a method for producing an assembly comprising at least a first part and at least one crosslinked bonded joint obtained using such a thermoplastic adhesive or such a composition.
