Abstract:
A polymerization catalyst composition comprising a catalyst activator and a Ti, Zr, Hf, V, Mn or Cr complex of an anion of the formula (I) wherein:R1 is hydrocarbyl or substituted hydrocarbyl, R2 is hydrogen, hydrocarbyl or substituted hydrocarbyl, and R3 is hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group, provided that R1 and R2 taken together may be ortho-arylene or substituted ortho-arylene, or R1, R2 and R3 taken together may form one or more rings; Z is a bridging group of the formula (II), (III) or (IV) Q is nitrogen, oxygen, phosphorous or sulfur, provided that when Z is (II), Q is oxygen; R4 is hydrogen, hydrocarbyl or substituted hydrocarbyl, provided that when Q is oxygen or sulfur R4 is not present; R6 is hydrogen, hydrocarbyl or substituted hydrocarbyl, provided that R3 and R6 together may form a ring; R7 is hydrogen, hydrocarbyl or substituted hydrocarbyl, provided that R3, R6 and R7 together may form an aromatic ring, or R6 and R7 taken together may form a ring; R8 is hydrogen, hydrocarbyl or substituted hydrocarbyl; R9 is hydrogen, hydrocarbyl or substituted hydrocarbyl, provided that R4 and R9 taken together may be part of a double bond to an imino nitrogen atom, or R8 and R9 taken together may form a carbonyl with the carbon to which they are attached, or R8 and R9 taken together may form a ring, or R4 and R9 taken together may form a ring, or R4, R8 and R9 taken together may form a ring, or R6, R7, R8 and R9 taken together may form an aromatic ring; R10, R11, R12 and R13 are each independently hydrogen, hydrocarbyl or substituted hydrocarbyl, provided that R10, R11, R12 and R13 taken together may be ortho-arylene; R14 and R15 are each independently hydrogen, hydrocarbyl or substituted hydrocarbyl, provided that R14 and R15 taken together may form a carbonyl with the carbon to which they are attached, or R12, R13, R14, and R15 taken together may form an o-arylene group, or R10, R11, R12, R13, R14, and R15 taken together may form a fused aromatic ring system, or R13 and R14 taken together may form a ring; R20 and R21 are each independently hydrogen, hydrocarbyl or substituted hydrocarbyl, or R20 and R21 taken together may form a ring; each R22 is individually hydrocarbyl, oxygen or alkoxy, provided that when R22 is oxygen, two of R22 are taken together to form T=O; n is an integer of 1 or more; T is phosphorous or sulfur whose oxidation state is 3 or greater; and x is equal to the oxidation state of T minus 2.
