Patent ID: 7998895

Claim:
A polymerization catalyst component comprising a Group 3 through 11 transition metal or lanthanide metal complex of a ligand of the formula wherein: R 1 and R 2 are each independently hydrocarbyl, substituted hydrocarbyl or a functional group; Y is CR 11 R 12 , S(T), P(T)Q, NR 36 or NR 36 NR 36 ; X is O, CR 5 R 6 or NR 5 ; A is O, S, Se, N, P or As; Z is O, Se, N, P or As; each Q is independently hydrocarbyl or substituted hydrocarbyl; R 3 , R 4 , R 5 , R 6 , R 11 and R 12 are each independently hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group; R 7 is hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group, provided that when Z is O or Se, R 7 is not present; R 8 and R 9 are each independently hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group; R 10 is hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group; each T is independently ═O or ═NR 30 ; R 30 is hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group; R 31 and R 32 are each independently hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group; R 33 and R 34 are each independently hydrocarbyl or substituted hydrocarbyl, provided that each is independently an aryl substituted in at least one position vicinal to the free bond of the aryl group, or each independently has an E s of −1.0 or less; R 35 is hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group, provided that when A is O, S or Se, R 35 is not present; each R 36 is independently hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group; m is 0 or 1; s is 1; n is 0 or 1; and q is 0 or 1; and provided that: any two of R 3 , R 4 , R 5 , R 6 , R 8 , R 9 , R 11 and R 12 bonded to the same carbon atom taken together may form a functional group; any two of R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 11 , R 12 , R 31 , R 32 , R 33 , R 34 , R 35 and R 36 bonded to the same atom or vicinal to one another taken together may form a ring; and when said ligand is (I), Y is C(O), Z is O, and R 1 and R 2 are each independently hydrocarbyl, then R 1 and R 2 are each independently an aryl substituted in one position vicinal to the free bond of the aryl group, or R 1 and R 2 each independently have an E s of −1.0 or less.
