Abstract:
A composition comprising a metallocene and a second metal compound which is represented by the formulae:((Z)XAt(YJ))qMQnâ€ƒâ€ƒ(I) or((Râ€²mZ)XAt(YJRâ€³m))qMQnâ€ƒâ€ƒ(II) wherein M is a metal selected from a group consisting of the Group 3 to 13 and the lanthanide and actinide series of the Periodic Table of Elements; Q is bonded to M and each Q is a monovalent, bivalent, or trivalent anion; X and Y are bonded to M; X and Y are independently carbon or a heteroatom, provided that at least one of X and Y is a heteroatom; Y is contained in a heterocyclic ring J, wherein J comprises from 2 to 50 non-hydrogen atoms; Z is bonded to X, wherein in formula I, Z comprises 1 to 50 non-hydrogen atoms, and in formula II, Z is a hydrocarbyl group, optionally including one or more heteroatoms; t is 0 or 1; when t is 1, A is a bridging group joining X and J; q is 1 or 2; n is the oxidation state of M minus q minus 1 if Q is a monovalent anion, n is (the oxidation state of Mâ€”q)/2, if Q is a bivalent anion or n is (the oxidation state of Mâ€”q)/3 if Q is a trivalent anion; Râ€³ groups are bound to heterocyclic ring J and are independently selected from the group consisting of hydrogen, linear, branched or cyclic alkyl radicals, alkenyl radicals, alkynl radicals, alkoxy radicals, aryl radicals and aryloxy radicals, two or more Râ€³ groups may be joined to form a cyclic moiety, and optionally, an Râ€³ may be joined to A; Râ€² groups are bound to Z and are independently selected from group consisting of hydrogen, linear or branched alkyl radicals, cyclic alkyl radicals, alkenyl radicals, alkynl radicals, and aryl radicals, two or more Râ€² groups may be joined to form a cyclic moiety, and optionally, an Râ€² group may be joined to A; and each m is independently an integer from 0 to 5.
