    • A process for the production of an ionic transition metal catalyst in supported form than is highly productive under gas phase olefin polymerization conditions. In the process a an aluminum alkyl is added to a suitable solvent after which a neutral metallocene compound is added to the solution under stirring in a quantity that provides for a ratio of Al to transition metal of at least 25:1. To this metallocene-aluminum alkyl solution is next added an ionic compound the anionic portion of which is a non-coordinating anion under stirring until all materials are dissolve. The ionic compound is added in a quantity that provides for a ratio of NCA to transition metal of at least 1:1. Next the support particles are added to the solution and thereafter the solution is heated to at lest 40 DEG C and held at this elevated temperature for at least 0.5 hour. Thereafter the solvent is removed and the supported catalyst is dried under vacuum.
    • 制备负载形式的离子过渡金属催化剂的方法比在气相烯烃聚合条件下高生产率的方法。 在该方法中,将烷基铝加入到合适的溶剂中,然后在搅拌下将中性茂金属化合物加入到溶液中,其量提供至少25:1的Al与过渡金属的比例。 接着向该茂金属 - 铝烷基溶液中加入离子化合物,其阴离子部分在搅拌下为非配位阴离子,直至所有物质溶解。 以提供至少1:1的NCA与过渡金属的比率的量加入离子化合物。 接着将载体颗粒加入到溶液中,然后将溶液加热至至少40℃,并在该升高的温度下保持至少0.5小时。 然后除去溶剂,将负载型催化剂真空干燥。

    • A process for producing a functional styrene copolymer which comprises causing a metal compound to act on a vinyl compound having a functional group to mask the functional group and copolymerizing the resultant vinyl compound with a styrene compound in the presence of a polymerization catalyst comprising (A) a transition metal compound and (B) an oxygenic compound and/or a compound capable of forming an ionic complex upon reaction with the transition metal compound and optionally containing (C) an organometallic compound. By the process, a functional styrene copolymer can be efficiently produced which is a random, block, or graft copolymer, especially preferably a random copolymer, of a vinyl compound having a functional group and a styrene compound, and in which repeating units derived from the styrene compound have a syndiotactic structure.
    • 一种功能性苯乙烯共聚物的制造方法,其特征在于,在含有(A)的聚合催化剂的存在下,使金属化合物作用于具有官能团的乙烯基化合物以掩蔽所述官能团并使所得乙烯基化合物与苯乙烯化合物共聚, 过渡金属化合物和(B)含氧化合物和/或能够与过渡金属化合物反应形成离子络合物并且任选地含有(C)有机金属化合物的化合物。 通过该方法,可以有效地制备作为具有官能团的乙烯基化合物和苯乙烯化合物的随机,嵌段或接枝共聚物,特别优选无规共聚物的功能性苯乙烯共聚物,其中衍生自 苯乙烯化合物具有间同立构结构。
