Abstract (en)

[origin: WO2004037898A1] The invention relates to polyamide block and polyether block copolymers in which: the polyether blocks essentially comprise PTMG having a number-average molar mass Mn of between 200 and 400 g/mol; the polyamide blocks comprise a linear (non-cyclic, non-branched) aliphatic semi-crystalline majority monomer and a sufficient quantity of at least one comonomer such that the crystallinity of said blocks is diminished while they remain immiscible with the amorphous polyether blocks; and the Shore D hardness is between 20 and 70. The inventive copolymers can be used to produce numerous different objects and, in particular, sports shoes.
