    摘要: This invention relates to an olefin polymerization catalyst composition comprising the product of the combination of at least one activator and at least two different transition metal compounds each of which is represented by the formula: ((Z)XAt(YJ))qMQn  (I) where M is a metal selected from Group 3 to 13 or lanthanide and actinide series of the Periodic Table of Elements; Q is bonded to M and each Q is a monovalent, divalent or trivalent anion; X and Y are bonded to M; X and Y are independently C or a heteroatom, provided that at least one of X and Y is a heteroatom and Y is contained in a heterocyclic ring J, where J comprises from 2 to 50 non-hydrogen atoms; Z is bonded to X, where Z comprises 1 to 50 non-hydrogen atoms; t is 0 or 1; when t is 1, A is a bridging group joined to at least one of X, Y or J; q is 1 or 2; n is the oxidation state of M minus q if Q is a monovalent anion, n is (the oxidation state of M−q)/2, if Q is a bivalent anion or n is (the oxidation state of M−q)/3 if Q is a trivalent anion.
