THREE COORDINATE ALUMINUM CATALYST ACTIVATOR COMPOSITION

摘要

Compounds corresponding to the formula: AlArQ<1>Q<2>, or a dimer, adduct, or mixture thereof and further mixtures with aluminum compounds of the formula: AlAr3, where: Ar is a fluorinated aromatic hydrocarbonyl moiety of from 6 to 30 carbon atoms; Q<1> is Ar or a C1-20 hydrocarbyl group, optionally substituted with one or more cyclohydrocarbyl, hydrocarbyloxy, hydrocarbylsiloxy, hydrocarbylsilylamino, hydrocarbylsilyl, silylhydrocarbyl, di(hydrocarbylsilyl)amino, hydrocarbylamino, di(hydrocarbyl)amino, di(hydrocarbyl)phosphino, or hydrocarbylsulfido groups having from 1 to 20 atoms other than hydrogen, or further optionally, such substituents may be covalently linked with each other to form one or more fused rings or ring systems; and Q<2> is an aryloxy, arylsulfide or di(hydrocarbyl)amido group, optionally substituted with one or more hydrocarbyl, cyclohydrocarbyl, hydrocarbyloxy, hydrocarbylsiloxy, hydrocarbylsilylamino, hydrocarbylsilyl, silylhydrocarbyl, di(hydrocarbylsilyl)amino, hydrocarbylamino, di(hydrocarbyl)amino, di(hydrocarbyl)phosphino, or hydrocarbylsulfido groups having from 1 to 20 atoms other than hydrogen, or, further optionally such substituents may be covalently linked with each other to form one or more fused rings or ring systems, said Q<2> having from 3 to 20 atoms other than hydrogen are useful as activators for olefin polymerizations.
