Abstract

The invention relates to modified polyamides, and more particularly to polyamides containing units of the type obtained by reacting a diacid with a diamine, modified with a multifunctional compound. The finished articles shaped from these polyamides or from compositions based on these polyamides have excellent mechanical properties and also a very good surface aspect. The modified polyamide according to the invention is obtained by melt-blending polyamides of different natures, in the presence of a multifunctional compound.
