    • Supported catalyst systems, methods of forming the supported catalyst systems and polymerization processes including the supported catalyst systems are described herein. The methods generally include providing an inorganic support composition, wherein the inorganic support composition comprises aluminum, fluorine and silica and contacting the inorganic support composition with a transition metal compound to form a supported catalyst system, wherein the transition metal compound is represented by the formula [L]mM[A]n; wherein L is a bulky ligand, A is a leaving group, M is a transition metal and m and n are such that a total ligand valency corresponds to the transition metal valency. The methods further include contacting the inorganic support composition, the transition metal compound, the supported catalyst system or combinations thereof with at least one compound represented by the formula XRn, wherein X is selected from Group 12 to 13 metals, lanthanide series metals or combinations thereof and each R is independently selected from alkyls, alkoxys, aryls, aryloxys, halogens, hydrides, Group 1 or 2 metals, organic nitrogen compounds, organic phosphorous compounds and combinations thereof and n is from 2 to 5.
    • 本文描述了负载型催化剂体系,形成负载型催化剂体系的方法和包括负载型催化剂体系的聚合方法。 所述方法通常包括提供无机载体组合物,其中无机载体组合物包含铝,氟和二氧化硅,并使无机载体组合物与过渡金属化合物接触以形成负载型催化剂体系,其中过渡金属化合物由式[ L] mM的[A] N; 其中L是大体积配体,A是离去基团,M是过渡金属,m和n使总配体的化合价对应于过渡金属的价态。 所述方法还包括使无机载体组合物,过渡金属化合物,负载的催化剂体系或其组合与至少一种由式XRn表示的化合物接触,其中X选自第12〜13族金属,镧系金属或其组合 并且每个R独立地选自烷基,烷氧基,芳基,芳氧基,卤素,氢化物,第1或2族金属,有机氮化合物,有机磷化合物及其组合,n为2至5。
