Abstract: The invention relates to a block copolymer comprising at least one rigid polyamide block and at least one flexible block, characterized in that the flexible block has an NH2/OH ratio of concentrations of amine chain ends to alcohol chain ends which is within the range from 30 to 150, said concentrations being measured by 1H NMR (TFanh./CD2Cl23). The invention also relates to the use of a flexible block for manufacturing a copolymer containing polyamide blocks and flexible blocks that is both hydrolysis-resistant and CO2-permeable, with a permeability to CO2 of at least 10 000 cm3/m2/24 h/atm for a 25 μm film of said copolymer, characterized in that said flexible block has a ratio of amine chain ends to acid chain ends which is within the range from 30 to 150.

Abstract: The present invention relates to a copolymer with a rigid polyamide block and a flexible polyether or polyester block, wherein said polyamide block is semicrystalline and consists of a copolyamide of W/Y.Z type, wherein: (i) W is a lactam or an alpha, omega-aminocarboxylic acid; (ii) Y is a cycloaliphatic diamine; (iii) Z is an aliphatic and/or aromatic dicarboxylic acid; and the W/Y.Z molar ratio is between 10/1 and 27/1 limits excluded.

Abstract: The invention relates to a copolymer having polyamide PA blocks and polyether PE blocks, in which PA is of diamine.diacid X.Y type; X, the number of carbons of the diamine, is within the range from 6 to 14, and Y, the number of carbons of the diacid, is within the range from 6 to 18. The invention also relates to the use of the said copolymer in a process of direct adhesion between two TPE materials for increasing the peel strength between these materials.
