Abstract (en)
[origin: WO2019008288A1] The invention relates to the use of at least one impact modifier having a refractive index IR1 in a polyamide matrix consisting of a mixture of amorphous polyamide and semicrystalline polyamide, said matrix having a refractive index IR2, the difference in absolute value of IR1 - IR2 not exceeding 0.006, to produce a transparent composition having a fatigue strength, under the fatigue test referred to as notched "Ross-Flex", greater than 50 000 at -10°C.
