Patent ID: 7049378

Claim:
A process for the polymerization of olefins, comprising the step of contacting, at a temperature of about −100° C. to about +200° C., one or more monomers selected from the group consisting of ethylene and an olefin of the formula H 2 C═CH(CH 2 ) n G (XVII), with an active catalyst comprising a Group 3 to Group 10 transition metal complex, wherein the transition metal complex comprises no more than one anion having the formula (I) wherein: R 1 is hydrocarbyl or substituted hydrocarbyl, and R 2 is hydrogen, hydrocarbyl or substituted hydrocarbyl, and provided that R 1 and R 2 taken together may be ortho-arylene or substituted ortho-arylene; R 3 is hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group, provided that when R 1 and R 2 taken together are ortho-arylene or substituted ortho-arylene, R 3 may form a fused ring system therewith; Q is nitrogen, oxygen, phosphorous or sulfur; R 4 and R 5 are each independently hydrogen, hydrocarbyl, or substituted hydrocarbyl, provided that R 4 and R 5 taken together may form a ring, and further provided that when Q is oxygen or sulfur R 5 is not present; Z is a bridging group of the formula (II) or (III) R 6 is hydrogen, hydrocarbyl or substituted hydrocarbyl, provided that R 3 and R 6 together may form a ring; R 7 is hydrogen, hydrocarbyl or substituted hydrocarbyl, provided that R 3 , R 6 and R 7 together may form an aromatic ring or R 6 and R 7 taken together may form a ring; R 8 is hydrogen, hydrocarbyl or substituted hydrocarbyl; R 9 is hydrogen, hydrocarbyl or substituted hydrocarbyl, provided that R 4 and R 9 taken together may be part of a double bond to an imino nitrogen atom, or R 8 and R 9 taken together may form a ring, or R 4 , R 5 , R 8 and R 9 taken together may form an aromatic ring, or R 4 and R 9 taken together may form a ring, or R 4 , R 8 and R 9 taken together may form a ring; R 10 , R 11 , R 12 and R 13 are each independently hydrogen, hydrocarbyl or substituted hydrocarbyl or R 10 , R 11 , R 12 and R 13 taken together are ortho-arylene; R 14 is hydrogen, hydrocarbyl or substituted hydrocarbyl; R 4 and R 15 together are part of a double bond to an imino nitrogen atom; n is an integer of 1 or more; G is hydrogen, —CO 2 R 16 or —C(O)NR 16 2 ; and each R 16 is independently hydrogen, hydrocarbyl or substituted hydrocarbyl.
