Abstract: The present invention relates to manufactured articles consisting of the coupling of at least two polyamide-based parts, one of which consists of a polyamide matrix, preferably loaded with a dispersed filler, and the other consists of a polyamide matrix reinforced with fibres in their turn made of polyamide. The invention also relates to a process for the production of these manufactured articles. The manufactured articles of the invention have high mechanical strength but, unlike similar manufactured articles, they are made of a single polymer.

Abstract: The present invention relates to a polyamide and a process for the preparation thereof, and to compositions containing it. It relates more particularly to a polyamide obtained by polymerization of diacid and diamine monomers in the presence of multifunctional and monofunctional compounds capable of forming an amide function by reaction with either an aminated function or an acid function. This polyamide can in particular be used for the preparation of compositions intended, for example, to be moulded.

Abstract: Heat and light-stabilized polyamide compositions containing a stabilization system that includes copper oxide and KBr, and have an excellent preservation of color and of the mechanical properties thereof after exposure to heat or to light; these compositions are especially useful for producing shaped articles in the automotive field.

Abstract: Polyamide compositions and articles shaped therefrom have good dimensional stability and contain at least one novolac resin and nanometric flake structure filler material; the articles shaped therefrom, e.g., by injection molding, are useful in a various of applications, for example as engineering plastics.

Abstract: A process for producing an article, including: forming an article from a composition comprising a polyamide matrix, wherein the composition comprises: 2 to 10% by weight of carbon black as an electrically conductive filler, with respect to the total weight of the composition, and 1% to 30% by weight of an antistatic agent comprising a polyetheramide, with respect to the total weight of the composition; and applying paint to the article by electrostatic deposition.
