Abstract: The present invention relates to a process for forming a polymeric composition composed of a fluoropolymer and of zinc oxide (ZnO) of nanometric size from an acrylic masterbatch. The polymeric composition is intended for the manufacture of films transparent in the visible region and opaque to UV radiation. More particularly, in the composition according to the invention, the filler is present in a proportion by weight of 0.1 to 10%, preferably of 0.5 to 6%, the ZnO particles have a size ranging from 25 to 40 nm, preferably from 30 to 35 nm, these particles have a surface treatment and the said composition is devoid of acrylic polymers.

Abstract: 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.

Abstract: The software generates the computer code of at least one part of a computer application, from a description of this part of the computer application by distributing this part among several code generators according to modifiable distribution rules. Each code generator translates the part of the description that it is provided with, in order to provide at least one part of the computer code in a respective language. The invention also relates to a software description language, notably of the type of an object-oriented language for computer application modeling. The invention also relates to a software enabling to graphically or textually build a computer application model, notably a computer application human-machine interface model, and to provide a description of the model in a software description language according to the invention.

Abstract: The invention relates to the use of a coextruded multilayer film for protecting a (lingo)cellulose material, wherein said multilayer film consists of the following arranged to each other layers: a surface layer (I) comprising PVDF and possibly PMMA in the form of the main components, an intermediate layer (II) comprising in the form of main components 0-60 PVDF parts, 40 to 100 PMMA parts, 0-25 acrylic elastomer parts, and 0-10 UV absorber parts, the totality thereof being equal to 100 parts, and an adhesive layer (III), which comprises a functional PMMA in the form of the main component and is arranged on the side of the (ligno)cellulose material.
