Title (EN) MAGNESIUM ALKOXIDE PARTICLE AND APPLICATION THEREOF
(FR) PARTICULE D'ALCOXYDE DE MAGNÉSIUM ET SON APPLICATION
(ZH) 一种烷氧基镁颗粒及其应用
Abstract: front page image
(EN) Provided are a magnesium alkoxide particle and an application thereof. The magnesium alkoxide particle contains the reaction product of the following components: 1) a magnesium powder, 2) a mixed alcohol, 3) a halogenating agent, and 4) a titanate compound. When the magnesium alkoxide particle is used for preparing a catalyst for olefin polymerization, the obtained catalyst has high activity, good particle shape and even distribution, and the polymer bulk density is notably improved.
(FR) L'invention concerne une particule d'alcoxyde de magnésium et une application de celle-ci. La particule d'alcoxyde de magnésium contient le produit de réaction des composants suivants : 1) une poudre de magnésium, 2) un alcool mélangé, 3) un agent d'halogénation, et 4) un composé de titanate. Lorsque la particule d'alcoxyde de magnésium est utilisée pour préparer un catalyseur pour la polymérisation d'oléfines, le catalyseur obtenu présente une activité élevée, une bonne forme de particule et une distribution uniforme, et la densité apparente du polymère est particulièrement améliorée.
(ZH) 提供一种烷氧基镁颗粒及其应用。所述烷氧基镁颗粒包括下述组分的反应产物:1)镁粉、2)混合醇、3)卤化剂和4)钛酸酯类化合物。所述烷氧基镁颗粒用于制备烯烃聚合用催化剂时,得到的催化剂活性高,颗粒形态好,且分布均匀,聚合物堆积密度得到显著提高。
