A method relating to a copolymer containing rigid polyamides blocks and flexible blocks including, relative to the total weight of the copolymer: from 55% to 90% by weight of flexible blocks, including at least 35% by weight from polyethylene glycol; from 10% to 45% by weight of rigid polyamide blocks, in which the mean carbon content of the repeating units of the polyamide blocks is greater than or equal to 7. A method also relating to a process for preparing such a copolymer, to a membrane including such a copolymer and to a process for preparing such a membrane. |
