【発明の名称】アルミノキセートアニオンに連結した遷移金属カチオンからなる化合物及び触媒成分としての使用
Document Type and Number:
Japanese Patent JP2002528572
Kind Code:
A
Abstract:
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 extememly 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.
