摘要： The invention relates to a method for the preparation of a solid procatalyst composition for a catalyst system intended for the polymerization of olefins, wherein a magnesium halide, such as magnesium chloride, is dissolved and/or slurried in a monocarboxylic acid alkyl ester, such as ethyl acetate, is impregnated into a support material, dried, treated with an organometallic compound or a silicon compound and thereafter with a transition metal compound. The invention also relates to such a procatalyst composition and its use together with a cocatalyst for the polymerization of olefins. According to the invention it has been possible to increase the activity of the catalyst composition by using a silanated support material, such as silanated silica, which is then treated with an organometallic or silicon compound before treatment with a transition metal compound. The silanated silica is preferably a silicon dioxide which has been heat-treated at 100-200 DEG C and thereafter treated with hexamethyldisilazane and contains carbon 3-6 %. The organometallic compound is preferably an aluminum alkyl compound, such as triethylaluminum, and the transition metal compound is preferably titanium tetrachloride.

摘要： The invention relates to a process for the preparation of a solid procatalyst composition of catalyst system for the polymerization of olefins wherein a magnesium halide such as magnesium chloride is dissolved and/or suspended into an alkyl ester of a monocarboxylic acid such as ethyl acetate, impregnated to a carrier, treated with an organometallic compound or a silicon compound and thereafter with a transition metal compound. The invention also relates to a procatalyst composition and its use together with a cocatalyst for the polymerization of olefins. The activity has been enhanced according to the invention by the use of a carrier containing hydroxyl groups, which carrier is kept at a temperature of at most about 200 DEG C prior to the impregnation so that the hydroxyl groups are retained in the carrier to an essential extent until the impregnation step. The carrier is preferably silica which is treated thermally at 100-200 DEG C so that the water present is removed but the hydroxyl groups are retained to a considerable extent. The organometal compound is preferably an aluminumalkyl compound such as triethylaluminum, and the transition metal compound is preferably titanium tetrachloride.

摘要： Atactic polypropylene is produced by slurry-polymerizing propylene with the aid of a Ziegler-Natta catalyst system wherein the carrier is a chlorinated organic magnesium compound. The catalyst system is prepared in that the above-obtained solid component is refluxed with hot TiCl4 solution, and the product thus obtained is fed together with trialkylaluminium under slurry conditions into propylene in order to obtain an atactic polymer.

摘要： Provided are heterogeneous catalysts for homo- and copolymerization of olefins as well as a method for preparing these catalysts, which comprise at least one metallocene compound of a Group 4A, 5A or 6A (Hubbard) transition metal on a solid inorganic support. The method comprises the steps of vaporizing the metallocene compound, treating the support material with the vaporized metallocene compound at a temperature which is sufficiently high to keep the metallocene compound in the vaporous state, contacting the support material with an amount of the vaporized metallocene compound which is sufficient to allow for a reaction between the metallocene compound and at least a substantial part of the available surface sites capable of reacting therewith, removing the rest of the metallocene compound not bound to the support, and optionally treating the product thus obtained with an activating agent. The catalysts are active even if very low amounts of activator agents, such as alumoxane, are used. Furthermore, the polymerization performance of the catalysts can be regulated during the preparation of the catalysts. Thus, by using different support pretreatment temperatures, or by using two or more different metallocenes, and by altering the order in which they are added on the support, it is possible to control and regulate the activity of the catalysts and the polymer properties, such as molecular weight and molecular weight distribution.
摘要翻译：提供了用于烯烃均聚和共聚的非均相催化剂以及制备这些催化剂的方法，其包含至少一种在固体无机载体上的4A，5A或6A族（Hubbard）过渡金属茂金属化合物。该方法包括以下步骤：气化金属茂化合物，在足够高的温度下用汽化金属茂化合物处理载体材料以保持茂金属化合物处于气态，使载体材料与一定量的气化金属茂化合物接触，足以允许茂金属化合物与能够反应的至少大部分可用表面位点之间的反应，除去未结合到载体上的其余的金属茂化合物，以及任选地用活化的方法处理由此获得的产物剂。即使使用非常少量的活化剂如铝氧烷，催化剂也是有活性的。此外，可以在制备催化剂期间调节催化剂的聚合性能。因此，通过使用不同的载体预处理温度，或通过使用两种或更多种不同的金属茂，并通过改变其在载体上的添加顺序，可以控制和调节催化剂的活性和聚合物性质，例如作为分子量和分子量分布。
