  • Patent number: 10364351
    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: 10006586
    Abstract: The present invention relates to a gas storage tank, for storing gas, especially CNG, methane and/or hydrogen, said tank comprising a liner comprising a high-viscosity polyamide composition comprising a branched polyamide and an impact modifier, and to a process for manufacturing said the tank. More particularly, the composition comprises a copolyamide of the random tree type resulting from the reaction between a multifunctional monomer comprising at least three reactive functions to form an amide function, these functions being of two different types, difunctional monomers conventionally used in the manufacture of linear polyamides, and optionally difunctional monomers.

  • Publication number: 20170096513
    Abstract: Provided is a copolymer comprising from about 88 to about 92 mol % of a hydrophilic unit derived from N-vinylpyrrolidone and a cationic unit derived from a dimethyldiallylammonium salt, wherein the copolymer has a molar mass greater than or equal to 250,000 g/mol. Said copolymer is useful especially as a suds boosting polymer in hand dishwashing detergent compositions comprising a surfactant system, and provides improved foaming properties.

  • Patent number: 8927651
    Abstract: A high-viscosity polyamide composition including a branched polyamide is described. Also described, is a relationship between a high-viscosity polyamide composition and a composition including a copolyamide of a statistical tree type resulting from a reaction between a multifunctional monomer including at least three reactive functions in order to form an amide function. Further described, are three reactive functions of two different types and bifunctional monomers used in the manufacture of linear polyamides. A resulting copolyamide can have a very low melt flow index relative to the linear polyamide and improved impact resistance properties. Lastly, use of such a composition for extrusion blow-molding articles is described.
