Abstract: 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).
