Abstract (en)
[origin: WO2021074543A1] The invention relates mainly to a water-dispersible copolyamide including at least four distinct polyamide units, in which: at least one of said polyamide units comprises at least one sulphonate group, said polyamide sulphonate unit being present in a content of at least 15% by weight; and at least two of said polyamide units are derived from aliphatic monomers, it being understood that said copolyamide comprises at least 15% by weight of sulphonate monomer and comprises no more than 20% by weight of units derived from caprolactam. The invention also relates to a composition including said water-dispersible copolyamide, particularly in filament form.
