    摘要： A polyamide-based polymer composition including: a) 50% to 98% by weight of a transparent amorphous polyamide; b) 1% to 15% by weight of a polymer in the form of core-shell particles; and c) 1% to 15% by weight of a polyether block and polyamide block copolymer, wherein the polyether block and polyamide block copolymer has: as a 2 mm layer, a transmittance at 560 nm of 90% or more; and a refractive index that does not differ by more than 0.01 from that of the transparent amorphous polyamide and wherein the polymer in the form of core-shell particles has a refractive index that does not differ by more than 0.01 from that of the transparent amorphous polyamide. Also, a process for the manufacture of the composition, and the composition capable of being obtained by said process.
