Abstract: The invention relates to a cellular substance, the method of preparation and uses thereof, in particular as an absorbent substance, and in particular for the manufacture of sponges and other products for household use. The cellular substance of the invention comprises a mixture of fibers of a hydrophilic polymer, and at least one elastomer, and has a cellular structure formed by cells whose size is between 0.2 ?m and 10 mm, at least 1% of the cells, by volume as compared to the total cell volume, having a size of between 0.2 ?m and 10 ?m. The invention has application, particularly, in the area of absorbent products.

Abstract: The invention relates to a ribbed power transmission belt exhibiting a toothing made of elastomer based on ethylene/?-olefin elastomer, characterized in that at least the sides of the toothing are coated with a film made of at least partially crosslinked thermoplastic comprising at least 30% of at least one low-density polyethylene having a molecular weight of between 50 000 and 200 000 g/mol. The invention also relates to a manufacturing process which makes use of the application of a said thermoplastic film in the noncrosslinked or at least partially crosslinked state.

Abstract: The present invention relates to a multilayer elastomeric material having the property of attenuating radiation such as, for example, X-ray and gamma radiation, to its preparation method, and also to its use for manufacturing articles for protection against radiation, in particular X-ray and/or gamma radiation.

Abstract: The invention relates to a cross-linked composition comprising at least one elastomer and at least one triblock block sequenced copolymer. The Invention also relates to a method for obtaining one such composition based on a system and a suitably selected crosslinking temperature. According to a preferred embodiment of the invention, the cross-linked composition can be transformed as a thermoplastic material. The inventive composition can be used in various applications, especially for producing conduits for the transfer of fluids, seals and insulation linings.

Abstract: The present invention relates to a composition comprising at least two incompatible thermoplastic polymers and at least one compatibilizer, to a method of preparing this composition, and to the use of said composition for the manufacture of thermoplastic articles or semi-finished products having, in particular, improved mechanical properties. A composition according to the invention is such that said polymeric compatibilizer includes at least two groups of polar and apolar units compatible with the respectively polymers, and it is characterized in that it comprises the product of a hot compounding reaction, in the presence of a crosslinking system, of said compatibilizer in the crosslinkable state with said thermoplastic polymers, in such a way that only said compatibilizer is crosslinked in said composition.

Abstract: The present invention relates to a multilayer material made from elastomers and containing one or more active substances dispersed in the form of droplets, and also to its uses, especially as a glove, a finger stall, a condom, a tape or dressings.
