    摘要： The invention relates to is a crosslinked composition containing in parts by weight: 20 to 100 parts of at least one elastomer (I), 2 to 50 parts of at least one core/shell copolymer (II), and 0 to 100 parts of at least one thermoplastic polymer (III). The invention also relates to a method of producing one such crosslinked composition, which is characterized in that it consists in: mixing an elastomer and a core/shell copolymer optionally in the presence of: a grafted polyolefin, a plasticizer, fillers and/or additives, and a suitably-selected crosslinking system, and subsequently crosslinking said mixture at a suitable temperature. In a preferred embodiment of the invention, the mixture is crosslinked at a temperature of between 150 and 320° C. The invention method be carried out in an internal mixer, or, alternately, in a twin-screw extruder or a Buss®-type co-kneader. Depending on the case, the resulting mass is calendared or extruded, cooled and subsequently granulated. The granules thus obtained are then ready to be transformed, by means of heating, into sheets, plates, extrusions, tubes or other desired products. The invention further relates to the use of one such composition in the production of ducts, pipes, tubing, couplers or similar for conveying fluids, such as the fluid transfer conduits, pipes and other elements which are used in the automobile industry in braking, cooling, steering and air-conditioning systems. The inventive crosslinked composition can also be used in the production of belts, tires, electrical cable sheaths, and shoe soles.”

    摘要： The invention relates to a method for continuously and dynamically mixing at least two fluids. Said method comprises the following steps: a) the rotor (1) of a micromixer is rotatably driven, said micromixer comprising a rotor (1) which is provided with a shaft (2) encompassing blades (3) that are arranged in groups (3a-3g), a stator (4) which is provided with at least one inlet (5) for a first fluid, at least one inlet (6) for a second fluid, and an outlet (7); b) the fluids are fed into the micromixer; and c) a micromixture of the fluids is collected at the outlet (7) of the micromixer. The inventive method is particularly suitable for rapid and/or complex kinetic chemical reactions such as anionic polymerization. The invention also relates to a micromixer for carrying out said method.
