Abstract: front page image
(EN)A MgC12·mEtOH ·nH20 adducts, where 3.4< m≤4.4, 0≤n≤0.7, characterized by an X-ray diffraction spectrum, taken under the condition set forth above, in which, in the range of 2&thetas; diffraction angles between 5° and 10°, at least two diffraction lines are present at diffraction angles 2&thetas; of 9.3 ± 0.2°, and 9.9 ± 0.2°, the most intense diffraction lines being the one at 2&thetas; of 9.3 ± 0.2°, the intensity of the other diffraction line being less than 0.4 times the intensity of the most intense diffraction line.. Catalyst components obtained from the adducts of the present invention are capable to give catalysts for the polymerization of olefins characterized by enhanced activity and/or porosity with respect to the catalysts prepared from the adducts of the prior art.
(FR)L'invention concerne des composés d'addition MgCl2 mEtOH nH20, dans lesquels 3,4< m =4,4, 0 = n = 0,7. Ces composés d'addition sont caractérisés par un spectre de diffraction des rayons X remplissant les conditions formulées ci-dessus, dans lequel, dans une gamme d'angles de diffraction 2? compris entre 5° et 10°, au moins deux lignes de diffraction sont présentes, qui présentent des angles de diffraction 2? de 9,3 ± 0,2° et de 9,9 ± 0,2°, les lignes de diffraction les plus intenses étant celles à 2? de 9,3 ± 0,2°, l'intensité de l'autre ligne de diffraction étant inférieure à 0,4 fois celle de la ligne de diffraction la plus intense. Les composants de catalyse obtenus à partir des composés d'addition selon l'invention peuvent donner des catalyseurs pour la polymérisation d'oléfines caractérisés par une activité et/ou une porosité renforcées par rapport aux catalyseurs préparés à partir des composés d'addition de la technique antérieure.
