Patent number: 10364351Abstract: 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.Type: GrantFiled: April 10, 2012Date of Patent: July 30, 2019Assignee: RHODIA OPERATIONSInventors: Wojciech Bzducha, Franco Speroni, Christophe Lapierre

Patent number: 10006586Abstract: 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.Type: GrantFiled: October 8, 2013Date of Patent: June 26, 2018Assignee: Rhodia OperationsInventors: Wojciech Bzducha, Franco Speroni

Patent number: 8927651Abstract: 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.Type: GrantFiled: April 4, 2011Date of Patent: January 6, 2015Assignee: Rhodia OperationsInventors: Magali Davezac, Wojciech Bzducha
