  Transition metal compounds having conjugate aluminoxate anions and their use as catalyst components

  摘要：

  本文描述了一种新型高效催化剂组合物，其中可以在非常低的铝负载下使用低成本的共催化剂。这些化合物由d块或f块金属化合物衍生的阳离子组成，例如金属茂，通过失去一个离去基团，和由稳定或亚稳定羟基氧铝烷向此离去基团转移质子而得到的铝氧烷阴离子。这些催化剂组合物具有极高的催化活性，通常在烷基溶剂中具有高溶解度。此外，它们产生的灰分水平较低，从这些催化剂形成的聚合物中得到改善的透明度。令人惊讶的是，当在无水惰性条件和环境下分离、储存和可选地纯化这些催化剂化合物时，它们比保持在溶液中更稳定。因此，这些催化剂化合物可以在惰性无水条件下作为预制催化剂储存、运输和使用，从而简化了聚合操作。

  Gelatinous compositions of matter which are useful as polymerization catalyst components and are highly stable in terms of OH-decay rate, as well as similarly stable solid compositions of matter formed from such gelatinous compositions, are described. The gelatinous and solid compositions are formed from hydroxyaluminoxane. Also disclosed is a process comprising converting a hydroxyaluminoxane into a gelatinous composition of matter, whereby the rate of OH-decay for the composition is reduced as compared to that of the hydroxyaluminoxane. Olefin polymerization processes and catalysts formed from these novel compositions of matter also are disclosed.

  Novel, highly effective catalyst compositions are described in which a low cost co-catalyst can be employed at very low aluminum loadings. Such compounds are composed of a cation derived from d-block or f-block metal compound, such as a metallocene, by loss of a leaving group, and an aluminoxate anion derived by transfer of a proton from a stable or metastable hydroxyaluminoxane to such leaving group. These catalyst compositions have extremely high catalytic activity and typically have high solubility in paraffinic solvents. Moreover they yield reduced levels of ash and result in improved clarity in polymers formed from such catalysts. Surprisingly, when isolated and stored, and optionally purified, under anhydrous inert conditions and surroundings, the catalyst compounds are more stable than if kept in solution. Thus these catalyst compounds can be stored, shipped, and used under inert anhydrous conditions as preformed catalysts thus simplifying the polymerization operations. Substantial benefits are also realized by forming, and by using in the formation of activated catalysts, a hydroxyaluminoxane supported on a catalyst support or carrier.
