  • Polyetheresteramides and compositions of antistatic polymers containing the same
    Patent number: 6706851
    Abstract: The present invention relates to polyetheresteramides (B) containing polyamide blocks comprising dicarboxylic acid sulphonates either as polyamide-block chain limiters or combined with a diamine as one of the constituent monomers of the polyamide block, and containing polyether blocks consisting essentially of alkylene oxide units. The invention also relates to polyetheresteramides (B) containing polyamide blocks of the polyamide oligomer type of low molecular mass or of the copolyamide type which comprise dicarboxylic acid sulphonates and containing polyether blocks which are adducts of alkylene oxide with an aromatic diol. The invention also relates to antistatic or breathable polymer compositions comprising a thermoplastic polymer (A) and at least one of the above polyetheresteramides (B).

  • Copolymers containing polyamide blocks and polyether blocks based on ethoxylated amines
    Patent number: 6528615
    Abstract: 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.
