Copolymers containing polyamide blocks and polyether blocks based on ethoxylated amines

摘要

The present invention relates to copolymers containing polyamide blocks and polyether blocks based on ethoxylated primary amines, these copolymers having a melting point of between 80° C. and 135° C. and an MFI (melt flow index) of between 5 and 80 g/10 min (2.16 kg-150° C.).The invention also relates to adhesives of the HMA (or hot melt adhesive) type consisting of the above copolymers containing polyamide blocks and polyether blocks.
