Abstract (en)
[origin: WO2019110946A1] The invention relates to an outer cladding for an offshore hose, comprising at least one block copolymer containg at least one rigid polyamide block and at least one flexible block. The invention relates in particular to a flexible tubular pipe for conducting fluids in the field of offshore oil extraction, characterized in that said pipe comprises at least one such outer cladding. The invention also relates to the use of a block copolymer containing at least one rigid polyamide block and at least one flexible block, for manufacturing a part that is both resistant to hydrolysis and CO2-permeable, characterized in that the flexible block comprises amine chain ends.
