ABSTRACT:
A method for increasing at least one of the following two parameters of a polyamide: (I) its melting point and (ii) its enthalpy of melting ΔHm, in which:this polyamide is brought into contact in the solid state with water or with steam at a temperature close to its crystallization temperature Tcfor a time long enough to effect this increase;then, the water (or steam) is separated from the polyamide and the polyamide is dried.
