    摘要: The present invention relates to multilayer films made of fluoro polymers, which have properties that make them suitable for use in the agricultural field, especially as greenhouse covering films. According to a first aspect, the invention relates to multilayer fluorinated films comprising at least three layers, including a layer A made of a first vinylidene fluoride copolymer with a crystallization temperature TcA, and a layer B made of a second vinylidene fluoride copolymer with a crystallization temperature TcB, TcA being greater than TcB, layers A and B being alternating, layer A being placed to the exterior and layer B between two layers A. Another subject of the invention relates to the use of the film according to the invention as an agricultural covering material, especially as a greenhouse covering.

    摘要: An agent is provided which renders compatible at least two incompatible thermoplastic polymers. The agent contains one di- or trisequenced copolymer comprising at least one N-vinyl-pyrrolidone or methyl (meth) acrylate telomer and one mono- or difunctional oligomer selected from the group consisting of an ethylenically unsaturated polymerizable monomer, or a polycondensable monomer, or a lactam. The agent is prepared by condensation of the telomer with the oligomer and is used in the preparation of alloys of incompatible thermoplastic polymers.
