    • 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 C 3 to C 2o 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油包水乳液; 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。 可以制备适用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。
