Abstract
The invention relates to a method for converting a polycondensed elastomeric thermoplastic polymer, including a step of extruding the polycondensed elastomeric thermoplastic polymer in the presence of water. The polycondensed elastomeric thermoplastic polymer is in particular chosen from copolymer block amides, copolyethers or copolyester block urethanes, copolyether block esters and the mixtures thereof, and is preferably a copolyether block amide.
