Abstract:
A composition comprising:A) an aluminum compound corresponding to the formula AlAr.sup.f.sub.3, whereAr.sup.f is a fluorinated aromatic hydrocarbyl moiety of from 6 to 30 carbon atoms; andB) an aluminum compound corresponding to the formula: AlAr.sup.f Q.sup.1 Q.sup.2, or a dimer, adduct, or mixture thereof, where:Ar.sup.f is as previously defined;Q.sup.1 is Ar.sup.f or a C.sub.1-20 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 are covalently bonded to each other to form one or more fused rings or ring systems; andQ.sup.2 is an aryloxy, arylsulfido 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 1to 20 atoms other than hydrogen, or, further optionally such substituents are covalently bonded to each other to form one or more fused rings or ring systems, said Q.sup.2 having from 3 to 20 atoms other than hydrogen; andthe molar ratio of A):B) in the composition is from 0.1:1to 10:1.
