摘要： The supported catalyst according to the present invention comprises a support of organic or inorganic powder with a high-surface area, a polymer coated onto the support and a metallocene catalyst. The polymer (1) contains polar groups; (2) interacts with the surface of the support; and (3) is insoluble in the styrenic monomer or polymerization solvent during polymerization after the catalyst is loaded. The polymer is located between the support and the metallocene catalyst such that the polymer insulates the metallocene layer from the support layer to prevent poisoning of the metallocene catalyst layer by the support layer. The styrenic polymer powder such produced by the present invention has good flow-ability and good morphology demonstrating a great deal of industrial applicability.

摘要： The invention provides a method for producing soluble neodymium chloride complex using neodymium chloride aqueous solution as raw material, thereby avoiding the use of anhydrous neodymium chloride, simplifying the synthesis process and reducing the cost for synthesizing neodymium chloride complex. The neodymium chloride complex produced by this method is soluble not only in polar solvent, but also in nonpolar solvent. Such neodymium chloride complex also has good dissolvability in aliphatic hydrocarbon solvent which has relatively weaker solution power, and even in aliphatic hydrocarbon solvent with 6 or less carbon atoms which has even lower solution power. Since neodymium chloride complex is soluble in aliphatic hydrocarbon solvent, its transportation may be conducted, which is convenient for industrial application and contributes to improve the utilization efficiency of rare earth.

摘要翻译： 本发明提供了一种使用氯化钕水溶液作为原料生产可溶性氯化钕络合物的方法，从而避免使用无水氯化钕，简化合成过程并降低合成氯化钕络合物的成本。 通过该方法制备的氯化钕络合物不仅可溶于极性溶剂，而且可溶于非极性溶剂中。 这种氯化钕络合物在溶解力相对较弱的脂族烃溶剂中也具有良好的溶解性，甚至在具有6个或更少碳原子的脂族烃溶剂中具有更低的溶液功率。 由于氯化钕络合物可溶于脂族烃溶剂，因此可以进行运输，这对于工业应用是方便的，有助于提高稀土的利用效率。
