Abstract

The present invention relates to a translucent composition comprising : a) From 55 to 97.99% by weight, based on the total weight of the composition, of a semi-crystalline polyamide matrix comprising : - 45 to 99% by weight of a polyamide A based on the total weight of the matrix, wherein the C/N ratio of the polyamide A is greater than 6.5 - 1 to 55% by weight of a polyamide B based on the total weight of the polyamide matrix, wherein the C/N ratio of the polyamide A is greater than 6.5; polyamides A and B have, in absolute value, at least one difference in C/N ratios equal to | C/N ratio (A) - C/N ratio (B)| ≤ 3, the polyamide A comprising at least 45 mol of at least one unit comprising a number of carbon atoms between the amide functional groups (including the carbonyl of the amide) denoted C1, the polyamide B comprising at least 30 mol% of at least one unit comprising a number of carbon atoms between the amide functions (including the carbonyl of the amide) denoted C2, with at least one of the equations |C1-C2| ≤ 3 being fulfilled, if the polyamides A and B each comprise more than one C1 and/or more than one C2 ; b) from 2 to 25% by weight, preferably from 3 to 20%,based on the total weight of the composition, of short glass fibers; c) from 0.01 to 20% by weight, based on the total weight of the composition, of acid modified polymer impact modifier comprising three or more blocks of polyamide.
