Abstract
A composition including at least one polyamide polymer obtained from at least one reactive polyamide prepolymer including at least one chain extender (PA-All-PA), the polyamide polymer being prepared at a temperature Tno lower than the temperature melting temperature or glass transition temperature of the polymer and having a mean molecular weight Mn. The composition has a melt viscosity which can be modulated according to the temperature to which the composition is exposed, wherein the temperature is between Tand T, Tand Tbeing higher than T, and the melt viscosity ηor η'observed at the temperature Tor T, respectively, being lower than the melt viscosity ηor ηof the polyamide polymer, which does not include a chain extender and has the same mean molecular weight Mn(PA) observed at the same temperature Tor T. The composition includes one or more polyamides.
