    • Processes for preparing aluminoxane comprising: bringing into contact under reaction conditions in an inert atmosphere a liquid containing reaction mixture comprising: (i) a water in oil emulsion comprising water and at least one emulsifier in a first hydrocarbon solvent; and (ii) an organoaluminum compound capable of forming aluminoxane in a second hydrocarbon solvent; provided that the aluminoxane produced by the reaction is present in solution under the reaction conditions. In a preferred embodiment a support carrier for the aluminoxane: (i) is present during the contact step or (ii) is introduced following contact. A polymerization catalyst can be prepared wherein the support carrier is SiO2 and a Group 3 to Group 10 metal containing single site complex is mixed with the aluminoxane. Catalysts suitable for polymerizing an olefin such as ethylene or copolymerizing an olefin with at least one C3 to C20 alpha-olefin can be produced.
    • 制备铝氧烷的方法包括:在惰性气氛中在反应条件下使含有液体的反应混合物接触,所述反应混合物包含:(i)在第一烃溶剂中包含水和至少一种乳化剂的水包油乳液; 和(ii)能够在第二烃溶剂中形成铝氧烷的有机铝化合物; 条件是通过反应产生的铝氧烷在反应条件下存在于溶液中。 在优选的实施方案中,铝氧烷的载体载体:(i)在接触步骤期间存在,或(ii)在接触之后引入。 可以制备聚合催化剂,其中载体载体是SiO 2,并且第3族至第10族金属含有单位点络合物与铝氧烷混合。 可以制备适合于使烯烃如乙烯聚合或使烯烃与至少一种C 3至C 20α-烯烃共聚的催化剂。
