ABSTRACT:
This system for thermoplastic adhesives includes (A) a first composition without anhydride groups, containing: a) at least one polymer chosen from the thermoplastic polymers and the synthetic rubbers; b) at least one compound containing at least one group which can react with anhydride groups; c) at least one tackifying resin; and d) if desired, at least one plasticizer; (B) a second composition containing constituents Ba, Bc and Bd which are respectively analogous to the constituents Aa, Ac and Ad, and b) at least one polymer containing anhydride groups; and (C) at least one activator of the reaction between the reactive groups of Ab and the anhydride functions of Bb. Advantageously the activator (C) is wholly incorporated in the composition A and/or in the composition B, so as to form a two-component system.
