摘要：
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 the 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).
