Abstract
The present invention relates to the use of a mixture of at least one semi-crystalline aliphatic polyamide and at least one amorphous polyamide, wherein the at least one semi-crystalline aliphatic polyamide is obtained by polycondensation: of at least one Cto C, preferentially Cto C, more preferentially Cto Camino acid, or at least one Cto C, preferentially Cto C, more preferentially Cto Clactam, or at least one C-C, preferentially C-C, preferentially C-C, more preferentially C-Cdiamine Ca, with at least one C-C, preferentially C-C, preferentially C-C, more preferentially C-Cdicarboxylic acid Cb; in order to prepare a semi-crystalline composition, the modulus of which does not vary by more than 25% within the temperature range from 10° C. to 40° C.
