The invention pertains to A polyannide composition [composition (C)] comprising: - from 20 to 95 % wt of at least one polyamide [polyamide (A)]; - from 1 to 30 % wt of at least one branched polyamide different from polyamide (A), said branched polyamide comprising recurring units derived from polycondensation of a mixture [mixture (B)] comprising: - at least one polyamine monomer comprising at least three amine functional groups selected from the group consisting of secondary amine group of formula -NH- and primary amine group of formula -MH2 [monomer (FN)], and - ε-caprolactam (or derivates thereof); said branched polyamide possessing a concentration of amine end groups (AEG) and a concentration of carboxylic end groups (CEG) such that the difference AEG-CEG is of at least 100 meq/kg [polyamide (B)]; and - from 0.01 to 3.5 % wt of at least one thermal stabilizer [stabilizer (S)], - optionally, from 0 to 60 % wt of at least one filler [filler (F)]; - optionally, from 0 to 20 % wt of at least one impact modifying rubber [rubber (I)]; - optionally, from 0 to 20 % wt of other conventional additives, with above % wt being referred to the total weight of composition (C). |
