Abstract (en)
[origin: WO2016097342A1] One subject of the present invention is a copolymer comprising: - from 5 to 50% by weight, relative to the total weight of the copolymer, of at least one polyamide (PA) block, - from 20 to 94% by weight, relative to the total weight of the copolymer, of at least one polyethylene glycol (PEG) block, - from 1 to 45% by weight, relative to the total weight of the copolymer, of at least one block more hydrophobic than the PEG block, said block more hydrophobic than the PEG block being selected from a polyether (PE) block different from the PEG, a polyester (PES) block and a polyolefin (PO) block. Another subject of the present invention is a process for synthesizing said copolymer.
