Abstract:
A hot melt adhesive comprising copolymers containing (A) polyamide blocks and (B) polyether blocks produced from reactants comprising an ethoxylated primary amine, said polyamide blocks (A) having a number average molecular mass between 300 and 15,000 and said polyether block (B) having a number average molecular mass of between 100 and 6000, (A) and (B) being present in a ratio in the copolymers to provide a melting point of between 80Â° C. and 135Â° C. and having been prepared with a sufficient amount of a dicarboxylic acid to yield an MFI (melt flow index) of between 5 and 80 g/10 min (2.16 kg-150Â° C.).
