Abstract
The invention relates to injected components based on polyamide resin (A) and on at least one copolymer (B) of ethylene and of an unsaturated epoxide, the copolymer (B) being obtained by copolymerization or by grafting the epoxide. The copolymer (B) is advantageously an ethylene/alkyl (meth)acrylate/glycidyl (meth)acrylate copolymer. The melt flow index of the compositions containing (A) and (B) is greater than the ratio of the melt flow index of (A) over 0.175 times the weight percentage of (B).
