摘要：
A copolymer containing polyether (PE) block(s) and polyamide (PE) block(s) issued for the manufacture of a transparent article having high-velocity impact resistance, and impact strength. In said copolymer: PA blocks comprise more than 50 mol % of an equimolar combination of at least one cycloaliphatic diamine and of at least one aliphatic dicarboxylic acid having from 12 to 36 carbon atoms, represent 20 to 90% by weight, out of the total weight of the copolymer, have a number-average molecular weight of 1000 to 10 000 g/mol, and the PE blocks represent 10 to 80% by weight, out of the total weight of the copolymer, and have a number-average molecular weight of 200-1000 g/mol.
