    摘要: A metal surface is coated with a coating comprising, in succession starting from the metal: optionally, a primer layer; optionally, a tie layer; and a polyamide-based layer consisting of a blend of a polyamide and of a polyolefin functionalized by an unsaturated carboxylic acid anhydride. Advantageously, the metal surface is the outer surface of a tube, particularly a small-diameter pipe having, for example, an outside diameter of 4 to 50 mm. The metal may be any metal, but the coating is very useful for steel and its alloys and for aluminium and its alloys. The optionally, a tie layer; aluminium may be anodized. Thus, the coated surface can comprise aluminium, the anodizing layer, the optional primer, the optional tie and the PA-based layer. The steel may be coated with zinc or a Zn-based alloy (such as, for example, a ZnnullAl or ZnnullFe mixture) or with aluminium or an Al-based alloy and/or treated by chromatizing or phosphatizing. Thus, the coated surface can comprise steel, the optional zinc or aluminium layer, the optional chromatizing or phosphatizing treatment layer, the optional primer, the optional tie and the PA-based layer. Preferably, the chromatizing is carried out with CrIII.

    摘要: Butyl acrylate is prepared by reacting acrylic acid and butanol in a reactor in the presence of an esterification catalyst the water formed being entrained by distillation in a column (2) in the form of a heteroazeotropic mixture with butanol mixture following condensation, being separated in a decanter (3) to give an upper, organic phase which is recycled to the top of the distillation column (2) and a lower, aqueous phase which is drawn off. The reaction is conducted with deferred introduction of part of the butanol at the top of the distillation column (2) or to the decanter (3) or to the reactor (1), the butanol/acrylic acid molar ratio being initially between 0.5 and 1 before rising to between 1 and 1.5 following the completion of the deferred introduction of the butanol.

    摘要: The present invention relates to a lithium-ion battery element which is chosen from the separator and the electroactive layers and which results from the forming of a microcomposite powder comprising a fluoropolymer in the form of particles between 0.1 and 0.5 nullm in size and fillers. The present invention also relates to a lithium-ion battery electrode comprising the above electroactive layer combined with a metal layer. The present invention also relates to a lithium-ion battery comprising at least one element such as the separator, the electroactive layer or the electrode defined above. This microcomposite powder can be prepared by coatomization of an aqueous solution containing the fluoropolymer particles between 0.1 and 0.5 nullm in size and of an aqueous solution of the fillers. It can also be prepared by flocculation or coagulation of an aqueous solution containing the fluoropolymer particles between 0.1 and 0.5 nullm in size and of an aqueous solution of the fillers. The forming of this microcomposite powder consists in preferably forming a film in order to obtain an electrode film or a separator film. Next, these films are joined together to form a battery. This step (assembly, electrolyte filling, packaging, etc.) is known per se.
