Abstract:
A metallocene compound comprising one or more compounds represented by the following Chemical Formulae 1 or 2 in which at least one of the hydrogen radicals of R2, R3 or B is substituted by a radical selected from the group represented by the Chemical Formula 3:(C5R21)pB6(C5R2m)MQ3-p â€ƒâ€ƒ[Chemical Formula 1](wherein M is a transition metal of Group 4;(C5R21), (C5R2m) and (C5Rn2) are a cyclopentadienyl ligand, a substituted cyclopentadienyl ligand, a substituted cyclopentadienyl ligand in which two adjacent carbon atoms of a C5 are joined together to form one or more C4-C16 rings by a hydrocarbyl radical, in which each R2, which can be the same as or different from other R2, is a hydrogen radical, or an alkyl, cycloalkyl, aryl, alkenyl, alkylaryl, arylalkyl, or arylalkenyl radical having from 1 to 40 carbon atoms, or a metalloid of Group 14 substituted with hydrocarbyl radical; B is an alkylene carbon chain, arylene carbon chain, alkenylene carbon chain, dialkyl germanium, dialkyl silicon, alkyl phospine or alkyl amine radical substituting on and bridging two cyclopentadienyl ligands, or a cyclopentadienyl ligand and JR3z-y ligands by a covalent bond; R3 is a hydrogen radical, or an alkyl, alkenyl, aryl, alkylaryl, or arylalkyl radical having from 1 to 40 carbon atoms; J is an element of Group 15 or 16; each Q, which can be the same as or different from other Q, is a halogen radical, an alkyl, alkenyl, aryl, alkylaryl, or arylalkyl radical having from 1 to 20 carbon atoms, or an alkylidene radical having from 1 to 20 carbon atoms; L is a Lewis base; s is 0 or 1, p is 0, 1, or 2; (provided that p is 0 then s is 0; when s is 1 then l and m is 4; and when s is 0 then l and m is 5), and z is a valence number of J; provided that J is an atom of Group 15, then z is 3; and when J is an atom of Group 16, then z is 2; x is 0 or 1; provided that x is 0, then n is 5, y is 1, and w is greater than 0; when x is 1, then n is 4, y is 2, and w is 0), â€”(CR12)aâ€”OSiRbYc â€ƒâ€ƒ[Chemical Formula 3](wherein each R1, which can be the same as or different from other R1, is a hydrogen radical, or an alkyl, cycloalkyl, aryl, alkenyl, alkylaryl, arylalkyl, or arylalkenyl radical having from 1 to 40 carbon atoms,each R, which can be the same as or different from other R, is an alkyl, cycloalkyl, aryl, alkenyl, alkylaryl, arylalkyl, or arylalkenyl radical having from 1 to 40 carbon atoms, each Y, which can be the same as or different from other Y, is a hydrogen, halogen, alkoxy, aryloxy, or amide radical, a is an integral number from 1 to 40, c is 1, 2, or 3, and the sum of b and c is 3).
