| titleOfInvention | Hydrolysis-resistant, CO2-permeable block copolymers |
| abstract | The present invention relates to block copolymers comprising at least one rigid polyamide block and at least one flexible block, characterized in that the flexible blocks comprise as the concentration of amine chain ends to alcohol chain ends an NH2/OH ratio of 30 to 150, the concentrations were measured by 1 H NMR (TF anh ./CD 2 Cl 2 3 ). The invention also relates to the use of a flexible block for the manufacture of a copolymer comprising a polyamide block and a flexible block and which is both hydrolysis resistant and CO2 permeable, for a 25 mm thick film of said copolymer The CO2 permeability of the said flexible block is at least 10,000 cm3/m2/atm, characterized in that the ratio of the amine chain ends to the acid chain ends of the flexible block is 30 to 150. |
