Abstract (en)
[origin: WO2020188204A1] The present invention relates to the use of a copolyamide comprising at least two units of formula A/X 1 Y, wherein: A is a repeating unit obtained by polycondensation of at least one C 9 to C 18 , preferably C 10 to C 18 , more preferably C 10 to C 12 amino acid, or at least one C 9 to C 18 , preferably C 10 to C 18 , more preferably C 10 to C 12 lactam, or at least one C 4 -C 36 , preferably C 6 -C 18 , preferably C 6 -C 18 , more preferably C 10 -C 18 diamine Ca with at least one C 4 -C 36 , preferably C 6 -C 18 , preferably C 6 -C 18 , more preferably C 10 -C 18 diacid Cb; X 1 Y is a repeating unit obtained from the polycondensation of at least one C 4 to C 8 , preferably C 4 to C 6 , more preferably C 6 linear aliphatic diamine (X 1 ), and at least one aromatic dicarboxylic acid (Y), to prepare a composition comprising from 30 to 70% by weight of reinforcing fibers, relative to the total weight of the composition, and the modulus of which does not vary by more than 20% in the temperature range from 20°C to 40°C, in particular in the temperature range from 0°C to 40°C, more particularly in the temperature range from -10°C to 40°C. It also relates to a composition comprising such a copolyamide, a method for manufacturing the same, and molded articles obtainable therefrom.
