  • Publication number: 20140023808
    Abstract: The invention relates to a method for producing a tank having high fluid-barrier properties. According to the invention, a specific polyamide composition containing impact-resistance modifying agents is used in a first step to produce components by means of injection moulding and, subsequently, said components are assembled in order to obtain the tank. The viscosity and gasoline permeability of the polyamide composition are sufficient to allow the production of tanks that provide an excellent trade-off between fluid-barrier properties and mechanical properties.

  • Patent number: 8609765
    Abstract: A polymeric material from the styrene family comprises macromolecular chains grafted by nitrogen-containing heterocyclic groups; wherein the macromolecular chains comprise a polymeric backbone to which a grafted agent is attached by at least one covalent bond, the grafting agent comprises, in a single molecule, one or more associative groups capable of being bound by hydrogen bonds, and one or more reactive groups capable of forming covalent bonds with the polymeric backbone, at least one of the associative groups of the modifier is an imidazolidone heterocyclic ring. The mean number of imidazolidone groups to be inserted into the macromolecular chains is dependent both on the mean mass of said chains and on the final properties to be imparted to the material. Objects such as tubes, films, plates, stiffeners, bottles and containers can be made.
